Leviticus 25:37-39 The Voice (VOICE)
37 Do not ask for interest when you lend him money. Do not try to profit by selling him your food. 38 I am the Eternal One, your God, the One who led you out of Egypt so that I could give you the land of Canaan and be your God.
39 If your fellow citizen becomes so poor that he must sell himself to you as a slave, do not treat him as a slave.
