You shall not steal.
THOU SHALT NOT STEAL. Stealing implies taking money secretly. There are thieves who incur the death penalty, namely, those who kidnap an Israelite, be he a child or one who cannot speak clearly. The prohibition to steal money applies both to when the owner is present and to when he is not present. It also applies to cheating in number, measure, and weight. The term stealing also applies to what Absalom did, that is, it prohibits deceiving another person.
(יב) רַבִּי יוֹסֵי אוֹמֵר, יְהִי מָמוֹן חֲבֵרְךָ חָבִיב עָלֶיךָ כְּשֶׁלָּךְ, וְהַתְקֵן עַצְמְךָ לִלְמֹד תּוֹרָה, שֶׁאֵינָהּ יְרֻשָּׁה לָךְ. וְכָל מַעֲשֶׂיךָ יִהְיוּ לְשֵׁם שָׁמָיִם:
(12) Rabbi Yose said: Let the property of your fellow be as precious unto you as your own; Make yourself fit to study Torah for it will not be yours by inheritance; And let all your actions be for [the sake of] the name of heaven.
R. Shimon bar Kahanah was once assisting R. Eliezer. They passed a fence. [R. Eliezer] said to [R. Shimon]: "Bring me a woodchip to pick my teeth." He changed his mind and said: "Don't bring me anything." [R. Eliezer] said: "For if you bring it, others might follow my example and will cause the fence to be demolished!"
R. Haggai was once assisting R. Zeira. A man passed by carrying a load of wood. [R. Haggai] said to [R. Zeira]: "Bring me a woodchip to pick my teeth." He changed his mind and said: "Don't bring me anything, for if you bring it, others might follow my example and the man's load would be destroyed."
The Gemara relates another story regarding acknowledgement of the justice of divine punishment: Four hundred barrels of Rav Huna’s wine fermented and turned into vinegar, causing him great financial loss.
Rav Yehuda, the brother of Rav Sala the Pious, along with the Sages, and some say Rav Adda bar Ahava, along with the Sages, entered to visit him, and said: The Master should examine his actions, as perhaps he committed a transgression for which he is being punished.
Rav Huna said to them: Am I suspect in your eyes? Have I committed a transgression on account of which you advise me to examine my behavior?
They said to him: Is the Holy One, Blessed be He, suspect that He exacts punishment without justice? Your loss was certainly just, and you must examine your conduct to find out why. The Sages were aware of a flaw in Rav Huna’s conduct, to which they alluded (Tosafot). Rav Huna said to them: If someone has heard something improper that I have done, let him say so. They said to him: We have heard that the Master does not give a share of his grapevines to his tenant farmers. A tenant farmer is entitled to a portion of the crop grown on his landlord’s property, as well as a share of the vines planted during a given year. Rav Huna said to them: Does this tenant farmer leave me anything from the produce that he grows on my property? He steals it all. Consequently, in denying him his share of the grapevines I am simply recouping that which was stolen from me by this tenant farmer. They said to him: That is the meaning of the folk saying: One who steals from a thief has a taste of theft. Despite the fact that the property was stolen to begin with, one nevertheless engages in theft. Although he did not violate a prohibition per se, it is still a form of theft, and one who is held to a higher standard than others will be punished for it.
He said to them: I accept upon myself to give my tenant farmer his portion in the future.
Thereupon, as a result of Rav Huna’s repentance, God restored his loss. Some say his vinegar turned back into wine, and some say that the price of vinegar rose and it was sold at the price of wine.
