Talmud sur Job 6:14

HALAKHAH: “If somebody says to another: go and marry me preliminarily to woman X,” etc. He looks out for himself and is rewarded since his acquisition is valid, but he behaved treacherously⁵Babli 58b.. The same holds for monetary transactions. If somebody says to another: go and buy for me goods X, and [the agent] went and bought [the merchandise] for himself, he looks out for himself and is rewarded since his acquisition is valid, but he behaved treacherously⁶The Babli, 59a, agrees in general but points out that an agent must have some flexibility in warding off claims by third parties; it might be to the advantage of the principal if the agent acquires for himself rather than let the property fall into hostile hands.. Rebbi Ze‘ira cursed those who saw another person trying to buy certain goods and outbid him. Rebbi Abun in the name of Rebbi Ze‘ira: Also about one who organizes a group against another⁷S. Lieberman [Tarbiz 4 (1937), p. 379] explains that simply by having a group of people showing interest, even if no competing bid ensues, the hand of the seller is strengthened and the buyer forced to increase his bid., the rabbis quote: “A person who prevents a good thing coming to his neighbor abandons the fear of the Almighty.⁸Job 6:14, interpretation of Targum. (In a Genizah fragment: “The rabbis of Caesarea quote.”)”

“A person should not raise a dog unless it is tied by a chain.” Rebbi Yose ben Rebbi Ḥanina said: About anybody who raises a biting dog the verse says: “He who refuses kindness to his neighbor,¹⁰⁴Job 6:14; Babli Šabbat 63a/b. As Eliahu Fulda explains, a biting dog will frighten away the poor who cannot come and ask for alms.” etc.
