Leviticus 19:32-37

32"You shall stand up before the gray head and honor the face of an old man, and you shall fear your God: I am the Lord.

33"When a stranger sojourns with you in your land, you shall not do him wrong.

34You shall treat the stranger who sojourns with you as the native among you, and you shall love him as yourself, for you were strangers in the land of Egypt: I am the Lord your God.

35"You shall do no wrong in judgment, in measures of length or weight or 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.

37And you shall observe all my statutes and all my rules, and do them: I am the Lord."
