a. It is, namely, impossible to go suddenly from one extreme to the other: it is therefore according to the nature of man impossible for him suddenly to discontinue everything to which he has been accustomed. Now God sent Moses to make [the Israelites] a kingdom of priests and a holy nation (Exod. 19:6) by means of the knowledge of God. Comp. "Unto thee it was showed that thou mightest know that the Lord is God (Deut. 4:35); "Know therefore this day, and consider it in thine heart, that the Lord is God" (ibid. 5:39). The Israelites were commanded to devote themselves to His service; comp. "and to serve him with all your heart" (ibid. 11:13); "and you shall serve the Lord your God" (Exod. 23:25); "and ye shall serve him" (Deut. 13:5).
b. But the custom which was in those days general among all men, and the general mode of worship in which the Israelites were brought up, consisted in sacrificing animals in those temples which contained certain images, to bow down to those images, and to burn incense before them; religious and ascetic persons were in those days the persons that were devoted to the service in the temples erected to the stars, as has been explained by us. It was in accordance with the wisdom and plan of God, as displayed in the whole Creation, that He did not command us to give up and to discontinue all these manners of service; for to obey such a commandment it would have been contrary to the nature of man, who generally cleaves to that to which he is used;
c. it would in those days have made the same impression as a prophet would make at present if he called us to the service of God and told us in His name, that we should not pray to Him, not fast, not seek His help in time of trouble; that we should serve Him in thought, and not by any action. For this reason God allowed these kinds of service to continue; He transferred to His service that which had formerly served as a worship of created beings, and of things imaginary and unreal, and commanded us to serve Him in the same manner; viz., to build unto Him a temple; comp. "And they shall make unto me a sanctuary" (Exod. 25:8); to have the altar erected to His name; comp. "An altar of earth thou shalt make unto me" (ibid. 20:21); to offer the sacrifices to Him; comp. "If any man of you bring an offering unto the Lord" (Lev. 1:2), to bow down to Him and to burn incense before Him. He has forbidden to do any of these things to any other being; comp. "He who sacrificeth unto any God, save the Lord only, he shall be utterly destroyed" (Exod. 22:19); "For thou shalt bow down to no other God" (ibid. 34:14). He selected priests for the service in the temple; comp. "And they shall minister unto me in the priest's office" (ibid. 28:41). He made it obligatory that certain gifts, called the gifts of the Levites and the priests, should be assigned to them for their maintenance while they are engaged in the service of the temple and its sacrifices. By this Divine plan it was effected that the traces of idolatry were blotted out, and the truly great principle of our faith, the Existence and Unity of God, was firmly established; this result was thus obtained without deterring or confusing the minds of the people by the abolition of the service to which they were accustomed and which alone was familiar to them.
d. I know that you will at first thought reject this idea and find it strange; you will put the following question to me in your heart: How can we suppose that Divine commandments, prohibitions, and important acts, which are fully explained, and for which certain seasons are fixed, should not have been commanded for their own sake, but only for the sake of some other thing: as if they were only the means which He employed for His primary object? What prevented Him from making His primary object a direct commandment to us, and to give us the capacity of obeying it? Those precepts which in your opinion are only the means and not the object would then have been unnecessary.
e. Hear my answer, which win cure your heart of this disease and will show you the truth of that which I have pointed out to you. There occurs in the Law a passage which contains exactly the same idea; it is the following: "God led them not through the way of the land of the Philistines, although that was near; for God said, Lest peradventure the people repent when they see war, and they return to Egypt; but God led the people about, through the way of the wilderness of the Red Sea," etc. (Exod. 13:17). Here God led the people about, away from the direct road which He originally intended, because He feared they might meet on that way with hardships too great for their ordinary strength; He took them by another road in order to obtain thereby His original object. In the same manner God refrained from prescribing what the people by their natural disposition would be incapable of obeying, and gave the above-mentioned commandments as a means of securing His chief object, viz., to spread a knowledge of Him [among the people], and to cause them to reject idolatry. It is contrary to man's nature that he should suddenly abandon all the different kinds of Divine service and the different customs in which he has been brought up, and which have been so general, that they were considered as a matter of course; it would be just as if a person trained to work as a slave with mortar and bricks, or similar things, should interrupt his work, clean his hands, and at once fight with real giants. It was the result of God's wisdom that the Israelites were led about in the wilderness till they acquired courage.
f. For it is a well-known fact that travelling in the wilderness, and privation of bodily enjoyments, such as bathing, produce courage, whilst the reverse is the source of faint-heartedness: besides, another generation rose during the wanderings that had not been accustomed to degradation and slavery. All the travelling in the wilderness was regulated by Divine commands through Moses; comp. "At the commandment of the Lord they rested, and at the commandment of the Lord they journeyed; they kept the charge of the Lord and the commandment of the Lord by the hand of Moses" (Num. 9:23). In the same way the portion of the Law under discussion is the result of divine wisdom, according to which people are allowed to continue the kind of worship to which they have been accustomed, in order that they might acquire the true faith, which is the chief object [of God's commandments]. You ask, What could have prevented God from commanding us directly, that which is the chief object, and from giving us the capacity of obeying it? This would lead to a second question, What prevented God from leading the Israelites through the way of the land of the Philistines, and endowing them with strength for fighting? The leading about by a pillar of cloud by day and a pillar of fire by night would then not have been necessary. A third question would then be asked in reference to the good promised as reward for the keeping of the commandments, and the evil foretold as a punishment for sins. It is the following question: As it is the chief object and purpose of God that we should believe in the Law, and act according to that which is written therein, why has He not given us the capacity of continually believing in it, and following its guidance, instead of holding out to us reward for obedience, and punishment for disobedience, or of actually giving all the predicted reward and punishment? For [the promises and the threats] are but the means of leading to this chief object. What prevented Him from giving us, as part of our nature, the will to do that which He desires us to do, and to abandon the kind of worship which He rejects? There is one general answer to these three questions, and to all questions of the same character: it is this: Although in every one of the signs [related in Scripture] the natural property of some individual being is changed, the nature of man is never changed by God by way of miracle. It is in accordance with this important principle that God said, "O that there were such an heart in them, that they would fear me," etc. (Deut. 5:26). It is also for this reason that He distinctly stated the commandments and the prohibitions, the reward and the punishment. This principle as regards miracles has been frequently explained by us in our works: I do not say this because I believe that it is difficult for God to change the nature of every individual person; on the contrary, it is possible, and it is in His power, according to the principles taught in Scripture; but it has never been His will to do it, and it never will be. If it were part of His will to change [at His desire] the nature of any person, the mission of prophets and the giving of the Law would have been altogether superfluous.
g. I now return to my theme. As the sacrificial service is not the primary object [of the commandments about sacrifice], whilst supplications, prayers, and similar kinds of worship are nearer to the primary object, and indispensable for obtaining it, a great difference was made in the Law between these two kinds of service. The one kind, which consists in offering sacrifices, although the sacrifices are offered to the name of God, has not been made obligatory for us to the same extent as it had been before. We were not commanded to sacrifice in every place, and in every time, or to build a temple in every place, or to permit any one who desires to become priest and to sacrifice. On the contrary, all this is prohibited unto us. Only one temple has been appointed, "in the place which the Lord shall choose" (Deut. 12:26); in no other place is it allowed to sacrifice: comp. "Take heed to thyself, that thou offer not thy burnt-offerings in every place that thou seest" (ibid. 5:13); and only the members of a particular family were allowed to officiate as priests. All these restrictions served to limit this kind of worship, and keep it within those bounds within which God did not think it necessary to abolish sacrificial service altogether. But prayer and supplication can be offered everywhere and by every person. The same is the case with the commandment of ẓiẓit (Num. 15:38); mezuzah (Deut. 6:9; 11:20); tefillin (Exod. 13:9, 16); and similar kinds of divine service.
(4) Because of this principle which I explained to you, the Prophets in their books are frequently found to rebuke their fellow-men for being over-zealous and exerting themselves too much in bringing sacrifices: the prophets thus distinctly declared that the object of the sacrifices is not very essential, and that God does not require them. Samuel therefore said, "Hath the Lord as great delight in burnt-offerings and sacrifices as in obeying the voice of the Lord" (1 Sam. 15:22)? Isaiah exclaimed, "To what purpose is the multitude of your sacrifices unto me? saith the Lord" (Isa. 1:11); Jeremiah declared: "For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt-offering or sacrifices. But this thing commanded I them, saying, Obey my, voice, and I will be your God, and ye shall be my people" (Jer. 7:22, 23). This passage has been found difficult in the opinion of all those whose words I read or heard; they ask, How can Jeremiah say that God did not command us about burnt-offering and sacrifice, seeing so many precepts refer to sacrifice? The sense of the passage agrees with what I explained to you. Jeremiah says [in the name of God] the primary object of the precepts is this, Know me, and serve no other being; "I will be your God, and ye shall be my people" (Lev. 26:12). But the commandment that sacrifices shall be brought and that the temple shall be visited has for its object the success of that principle among you; and for its sake I have transferred these modes of worship to my name; idolatry shall thereby be utterly destroyed, and Jewish faith firmly established. You, however, have ignored this object, and taken hold of that which is only the means of obtaining it; you have doubted my existence, "ye have denied the Lord, and said he is not" (Jer. 5:12); ye served idols; "burnt incense unto Baal, and walked after other gods whom ye know not. And come and stand before me in this house" (ibid. 7:9-10); i.e., you do not go beyond attending the temple of the Lord, and offering sacrifices: but this is not the chief object.--I have another way of explaining this passage with exactly the same result. For it is distinctly stated in Scripture, and handed down by tradition, that the first commandments communicated to us did not include any law at an about burnt-offering and sacrifice. You must not see any difficulty in the Passover which was commanded in Egypt; there was a particular and evident reason for that, as will be explained by me (chap. xlvi.). Besides it was revealed in the land of Egypt; whilst the laws to which Jeremiah alludes in the above passage are those which were revealed after the departure from Egypt. For this reason it is distinctly added, "in the day that I brought them out from the land of Egypt." The first commandment after the departure from Egypt was given at Marah, in the following words, "If thou wilt diligently hearken to the voice of the Lord thy God, and wilt do that which is right in His sight, and wilt give ear to His commandments" (Exod. 15:26)." There he made for them a statute and an ordinance, and there he proved them" (ibid. ver. 25). According to the true traditional explanation, Sabbath and civil laws were revealed at Marah: "statute" alludes to Sabbath, and "ordinance" to civil laws, which are the means of removing injustice. The chief object of the Law, as has been shown by us, is the teaching of truths; to which the truth of the creatio ex nihilo belongs. It is known that the object of the law of Sabbath is to confirm and to establish this principle, as we have shown in this treatise (Part. II. chap. xxxi.). In addition to the teaching of truths the Law aims at the removal of injustice from mankind. We have thus proved that the first laws do not refer to burnt-offering and sacrifice, which are of secondary importance. The same idea which is contained in the above passage from Jeremiah is also expressed in the Psalms, where the people are rebuked that they ignore the chief object, and make no distinction between chief and subsidiary lessons. The Psalmist says: "Hear, O my people, and I will speak; O Israel, and I will testify against thee: I am God, even thy God. I will not reprove thee for thy sacrifices or thy burnt-offerings, they have been continually before me. I will take no bullock out of thy house, nor he-goats out of thy folds" (Ps. 50:29).--Wherever this subject is mentioned, this is its meaning. Consider it well, and reflect on it.
