Leviticus 19:32-37

32You are to rise in the presence of the elderly, honor the aged, and fear your God. I am the LORD.

33When a foreigner resides with you in your land, you must not oppress him. 34You must treat the foreigner living among you as native-born and love him as yourself, for you were foreigners in the land of Egypt. I am the LORD your God.

35You must not use dishonest measures of length, weight, or volume. 36You shall maintain honest scales and weights, an honest ephah,1 and an honest hin.2 I am the LORD your God, who brought you out of the land of Egypt.

37You must keep all My statutes and all My ordinances and follow them. I am the LORD.”
