Leviticus 19:35

33“‘If a stranger lives as a foreigner with you in your land, you shall not do him wrong.

34The stranger who lives as a foreigner with you shall be to you as the native-born among you, and you shall love him as yourself; for you lived as foreigners in the land of Egypt. I am the LORD your God.

35“‘You shall do no unrighteousness in judgment, in measures of length, of weight, or of quantity.

36You shall have just balances, just weights, a just ephah, and a just hin. I am the LORD your God, who brought you out of the land of Egypt.

37“‘You shall observe all my statutes and all my ordinances, and do them. I am the LORD.’”
