LEV810 The Talmud takes up the question of the morality of a breach of a verbal promise. It bases its conclusion on [this verse]. Why did the text mention the measure called "hin" in addition to the measure called "ephah"? Hin, according to Rabbi Judah, is a double-entendre. It is the name of a measure, and it also means "yes" in Aramaic. "It is to teach you that your yes should be just, and your no should be just" (Baba Metzia 40a). Man's words must be as honest as his scales.
