CLV(i)
14 You shall not extort from a humble and needy hireling, whether from your brothers or from your sojourner who is in your land, within your gates.
15 On his day you shall give him his hire, and the sun shall not set on it ( for he is humble, and to it he is lifting his soul) that he may not call against you to Yahweh, and it would become a sin on your part.
