Leviticus 19:9-10; 33-37; 23:22
“When you harvest the crops of your land, do not harvest the grain along the edges of your fields, and do not pick up what the harvesters drop. It is the same with your grape crop—do not strip every last bunch of grapes from the vines, and do not pick up the grapes that fall to the ground. Leave them for the poor and the foreigners living among you. I am the Lord your God.
"Do not take advantage of foreigners who live among you in your land. Treat them like native-born Israelites, and love them as you love yourself. Remember that you were once foreigners living in the land of Egypt. I am the Lord your God.
“Do not use dishonest standards when measuring length, weight, or volume. Your scales and weights must be accurate. Your containers for measuring dry materials or liquids must be accurate. I am the Lord your God who brought you out of the land of Egypt.
“You must be careful to keep all of my decrees and regulations by putting them into practice. I am the Lord.”
