Business Ethics

He said, “If you will heed the LORD your God diligently, doing what is upright in His sight, giving ear to His commandments and keeping all His laws, then I will not bring upon you any of the diseases that I brought upon the Egyptians, for I the LORD am your healer.”

You shall appoint magistrates and officials for your tribes, in all the settlements that the LORD your God is giving you, and they shall govern the people with due justice.

You shall not falsify measures of length, weight, or capacity.

You shall have an honest balance, honest weights, an honest ephah, and an honest hin.
I the LORD am your God who freed you from the land of Egypt.

You shall faithfully observe all My laws and all My rules: I am the LORD.

§ The Gemara further discusses weights and measures. The Sages taught: “You shall do no unrighteousness in judgment, in measure [bammidda], in weight, or in measure [uvamesura]” (Leviticus 19:35). The baraita defines these terms: “In measure [bammidda],” this is referring to measuring land, teaching that in order to measure land in a just manner one may not measure for one person in the summer when the measuring rope has become dry and short, and for one other individual in the rainy season, when the measuring rope is wet and limp, and therefore stretches more. “In weight” means that one may not cover his weights in salt, as salt erodes the weights, causing a loss for the buyer. “Or in measure [bamesura]” means that one may not cause liquid he is measuring to foam by pouring it speedily, as this results in a loss for the buyer, who receives less of the liquid than the amount for which he paid.

Rav Yeimar said to Rav Ashi: Why do I need the prohibition that the Merciful One wrote with regard to weights: “You shall do no unrighteousness in judgment, in measure, in weight, or in volume” (Leviticus 19:35)? It is merely another form of robbery. Rav Ashi said to him: It is referring to a seller who buries his weights in salt, in order to lighten them. Rav Yeimar said: That is the same as full-fledged robbery; therefore, it should not require a separate derivation. Rav Ashi answered: It is written to establish that he violates the prohibition from the moment of the act of burying them. He violates the prohibition even before he actually deceives a buyer with the buried weights.

MISHNA: A wholesaler [hassiton] must clean his measuring vessels, which are used for measuring liquids such as oil and wine, once every thirty days, because the residue of the liquids sticks to the measure and reduces its capacity. And a homeowner who sells his goods must clean his measuring vessels only once every twelve months. Rabban Shimon ben Gamliel says: The matters are reversed. In the case of one who is constantly using his vessels for selling merchandise the residue does not adhere to the measuring vessel, and therefore a wholesaler must clean his measures only once a year. But in the case of a homeowner, who does not sell as often, the residue adheres to the measuring vessel; therefore, he must clean them every thirty days.

When you sell property to your neighbor, or buy any from your neighbor, you shall not wrong one another.

אל תונו YE SHALL NOT WRONG [ONE ANOTHER] — This refers to wronging in money matters (Sifra, Behar, Section 3 4).

Both seller and buyer are forbidden to defraud each other, as it is written : "When you sell to your neighbor or buy from your neighbor, you shall not wrong each other" (Leviticus 25:14).— — Whether one has deceived deliberately or has not been aware of the fraud in a particular sale, he must repay.

GEMARA: The Sages taught: It is written: “And you shall not mistreat [tonu] one man his colleague; and you shall fear your God, for I am the Lord your God” (Leviticus 25:17). The tanna explains: The verse is speaking with regard to verbal mistreatment. The baraita proceeds: Do you say that it is speaking of verbal mistreatment [be’ona’at devarim], or perhaps it is speaking only with regard to monetary exploitation [be’ona’at mammon]? When it says in a previous verse: “And if you sell to your colleague an item that is sold, or acquire from your colleague’s hand, you shall not exploit [tonu] his brother” (Leviticus 25:14), monetary exploitation is explicitly stated. How then do I realize the meaning of the verse: “And you shall not mistreat one man his colleague”? It is with regard to verbal mistreatment.

Just as there is a prohibition against exploitation [ona’a] in buying and selling, so is there ona’a in statements, i.e., verbal mistreatment. The mishna proceeds to cite examples of verbal mistreatment. One may not say to a seller: For how much are you selling this item, if he does not wish to purchase it. He thereby upsets the seller when the deal fails to materialize. The mishna lists other examples: If one is a penitent, another may not say to him: Remember your earlier deeds. If one is the child of converts, another may not say to him: Remember the deeds of your ancestors, as it is stated: “And a convert shall you neither mistreat, nor shall you oppress him” (Exodus 22:20).

The Sages taught in a baraita: A person may not sell to another a sandal made from the hide of an animal that died of natural causes as though it were a sandal made from the hide of a healthy animal that was slaughtered. This is prohibited due to two factors: One, because he misleads the customer into thinking that the leather is of higher quality than it really is; and another, because of the danger involved, as it is possible that the animal died from a snakebite and the poison seeped into the part of the animal’s hide from which the sandal is made.

One who had water mix with his wine may not sell it in the store, unless he informs the buyer that it contains water. And he may not sell it to a merchant, even if he informs him of the mixture, as, although he is aware that there is water mixed with the wine, it will be used for nothing other than deceit because the merchant will likely not inform the buyer that it is diluted. In a place where they are accustomed to place water into the wine to dilute it and everyone is aware of that fact, one may place water in the wine.

One may not sift ground beans to remove the waste, lest he charge an inappropriately high price for the sifted meal, beyond its actual value; this is the statement of Abba Shaul. And the Rabbis permit doing so. And the Rabbis concede that one may not sift the meal only from the beans that are close to the opening of the bin to create the impression that the contents of the entire bin were sifted, as this is nothing other than deception. One may neither adorn a person before selling him on the slave market, nor an animal nor vessels that he seeks to sell. Rather, they must be sold unembellished, to avoid deceiving the buyer.

You shall not insult the deaf, or place a stumbling block before the blind. You shall fear your God: I am the LORD.

14) "and before the blind man do not place a stumbling-block.": before one who is "blind" in a certain matter. If someone asks you: "Is that man's daughter fit for (marriage into) the priesthood? Do not tell them that she is "kosher" if she is not. If they ask you for advice, do not give them advice that is unfit for them. Do not say: "Leave early in the morning," so that robbers should assault them. "Leave in the afternoon," so that they fall victim to the heat. Do not say to him "Sell your field and buy an ass," and you seek occasion against him and take (procure) it from him. Lest you say "But I gave him good advice!" — these things are "known to the heart," viz.: "And you shall fear your God; I am the Lord."

It was taught in the mishna that one may not exchange money from the trunks of customs collectors, which are assumed to include stolen funds. The Gemara questions this ruling: But doesn’t Shmuel say that the law of the kingdom is the law, i.e., halakha requires Jews to obey the laws of the state in which they live. Accordingly, the customs are collected legally and it should be permitted to make use of the funds.

When is the previous case applicable? When the tax collector is like a robber, like when an idolater or the tax collector that is standing above him or the one sent by the king, and there is no limit, rather, he takes as much as he wants and gives [to the king] as much as he wants. But the tax established by the king, and is he said he should take a third or a fourth, or any amount with a limit. And [if] he appoints a Jew to collect this part for the king and it is known that this person is trustworthy, and he does not add anything over what the king has decreed, he is not under the assumption that he is a robber, since the law of the king is law. Not only that, but one who transgresses and smuggles from this tax is stealing from the king, whether the king is an idolater or a Jewish king.
