אַל־תִּמְנַע־ט֥וֹב מִבְּעָלָ֑יו בִּהְי֨וֹת לְאֵ֖ל ידיך [יָדְךָ֣] לַעֲשֽׂוֹת׃
Não negues o bem a quem de direito, estando no teu poder fazê-lo.
Mishnah Bava Metzia
If one hired craftsmen and they deceived each other, they have no legally valid complaint against each other, but only cause for complaint. If one hired a donkey-driver or a wagon-driver to bring litter-bearers or pipers for a bride or for the dead, or laborers to take his flax out of the steep, or any matter that would be lost if delayed, and they retracted, if it was a place where there were no others [who could be hired for the same wage] he may hire others at their (the original workers) expense or he may deceive them.
