"הרבה ארבה עצבונך והרונך"

§ The Sages taught: There are three partners in the creation of a person: The Holy One, Blessed be He, and his father, and his mother. His father emits the white seed, from which the following body parts are formed: The bones, the sinews, the nails, the brain that is in its head, and the white of the eye. His mother emits red seed, from which are formed the skin, the flesh, the hair, and the black of the eye. And the Holy One, Blessed be He, inserts into him a spirit, a soul, his countenance [ukelaster], eyesight, hearing of the ear, the capability of speech of the mouth, the capability of walking with the legs, understanding, and wisdom. And when a person’s time to depart from the world arrives, the Holy One, Blessed be He, retrieves His part, and He leaves the part of the person’s father and mother before them. Rav Pappa said: This is in accordance with the adage that people say: Remove the salt from a piece of meat, and you may then toss the meat to a dog, as it has become worthless.

And Isaac entreated the LORD for his wife, because she was barren; and the LORD let Himself be entreated of him, and Rebekah his wife conceived. And the children struggled together within her; and she said: ‘If it be so, wherefore do I live?’ And she went to inquire of the LORD.

§ Rabbi Samlai taught: To what is a fetus in its mother’s womb comparable? To a folded notebook [lefinkas]. And it rests with its hands on its two sides of its head, at the temples, its two arms [atzilav] on its two knees, and its two heels on its two buttocks, and its head rests between its knees, and its mouth is closed, and its umbilicus is open. And it eats from what its mother eats, and it drinks from what its mother drinks, and it does not emit excrement lest it kill its mother. But once it emerges into the airspace of the world, the closed limb, i.e., its mouth, opens, and the open limb, its umbilicus, closes, as otherwise it cannot live for even one hour. And a candle is lit for it above its head, and it gazes from one end of the world to the other, as it is stated: “When His lamp shined above my head, and by His light I walked through darkness” (Job 29:3). And do not wonder how one can see from one end of the world to the other, as a person can sleep here, in this location, and see a dream that takes place in a place as distant as Spain [beAspamya]. And there are no days when a person is in a more blissful state than those days when he is a fetus in his mother’s womb, as it is stated in the previous verse: “If only I were as in the months of old, as in the days when God watched over me” (Job 29:2). And the proof that this verse is referring to gestation is as follows: Which are the days that have months but do not have years? You must say that these are the months of gestation. And a fetus is taught the entire Torah while in the womb, as it is stated: “And He taught me and said to me: Let your heart hold fast My words; keep My commandments, and live” (Proverbs 4:4). And it also states: “As I was in the days of my youth, when the converse of God was upon my tent” (Job 29:4). The Gemara asks: What is the purpose of the statement: And it also states: “When the converse of God was upon my tent”? Why is it necessary to cite this verse in addition to the previously quoted verse from Proverbs? The Gemara explains: And if you would say that the verse in Proverbs is insufficient, as it is a prophet who is saying that he was taught the entire Torah in his mother’s womb, but this does not apply to ordinary people, come and hear the verse in Job: “When the converse of God was upon my tent.” And once the fetus emerges into the airspace of the world, an angel comes and slaps it on its mouth, causing it to forget the entire Torah, as it is stated: “Sin crouches at the entrance” (Genesis 4:7), i.e., when a person enters the world he is immediately liable to sin due to his loss of Torah knowledge. And a fetus does not leave the womb until the angels administer an oath to it, as it is stated: “That to Me every knee shall bow, every tongue shall swear” (Isaiah 45:23). The verse is interpreted as follows: “That to Me every knee shall bow”; this is referring to the day of one’s death, as it is stated: “All those who go down to the dust shall kneel before Him” (Psalms 22:30). “Every tongue shall swear”; this is referring to the day of one’s birth, as it is stated in description of a righteous person: “He who has clean hands, and a pure heart, who has not taken My name in vain, and has not sworn deceitfully” (Psalms 24:4), i.e., he has kept the oath that he took before he was born. And what is the oath that the angels administer to the fetus? Be righteous and do not be wicked. And even if the entire world says to you: You are righteous, consider yourself wicked. And know that the Holy One, Blessed be He, is pure, and His ministers are pure, and the soul that He gave you is pure. If you preserve it in a state of purity, all is well, but if you do not keep it pure, I, the angel, shall take it from you.

If a woman is having trouble giving birth, they cut up the child in her womb and brings it forth limb by limb, because her life comes before the life of [the child]. But if the greater part has come out, one may not touch it, for one may not set aside one person's life for that of another.

And Antoninos said to Rabbi Yehuda HaNasi: From when is the soul placed in a person? Is it from the moment of conception or from the moment of the formation of the embryo, forty days after conception? Rabbi Yehuda HaNasi said to him: It is from the moment of the formation of the embryo. Antoninos said to him: That is inconceivable. Is it possible that a piece of meat could stand for even three days without salt as a preservative and would not rot? The embryo could not exist for forty days without a soul. Rather, the soul is placed in man from the moment of conception. Rabbi Yehuda HaNasi said: Antoninos taught me this matter, and there is a verse that supports him, as it is stated: “And Your Providence [pekudatekha] has preserved my spirit” (Job 10:12) indicating that it is from the moment of conception [pekida] that the soul is preserved within a person. And Antoninos said to Rabbi Yehuda HaNasi: From when does the evil inclination dominate a person? Is it from the moment of the formation of the embryo or from the moment of emergence from the womb? Rabbi Yehuda HaNasi said to him: It is from the moment of the formation of the embryo. Antoninos said to him: If so, the evil inclination would cause the fetus to kick his mother’s innards and emerge from the womb. Rather, the evil inclination dominates a person from the moment of emergence from the womb. Rabbi Yehuda HaNasi said: Antoninos taught me this matter, and there is a verse that supports him, as it is stated: “Sin crouches at the entrance” (Genesis 4:7), indicating that it is from the moment of birth, when the newborn emerges from the entrance of his mother’s womb, that the evil inclination lurks.
