Leviticus 19:32-37

32‘You shall rise before the gray headed and honor the presence of an old man, and fear your God: I am the Lord.

33‘And if a stranger dwells with you in your land, you shall not mistreat him.

34The stranger who dwells among you shall be to you as one born 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 injustice in judgment, in measurement of length, weight, or volume.

36You shall have honest scales, honest weights, an honest ephah, and an honest hin: I am the Lord your God, who brought you out of the land of Egypt.

37‘Therefore you shall observe all My statutes and all My judgments, and perform them: I am the Lord.’ ”
