Deuteronomy 24:14; Deuteronomy 24:15

14 "Do not cheat poor and needy hired servants, whether they are Israelites or foreigners living in one of your towns.

15 Each day before sunset pay them for that day's work; they need the money and have counted on getting it. If you do not pay them, they will cry out against you to the Lord, and you will be guilty of sin.
