Deuteronomy/Devarim 24:14–15
14 Do not oppress the hired laborer who is poor and needy, whether he is one of your people or one of the sojourners in your land within your gates. 15 Give him his wages in the daytime, and do not let the sun set on them, for he is poor, and his life depends on them, lest he cry out to God about you, for this will be counted as a sin for you.
