Leviticus 19:32-37

32You must stand up in the presence of the aged, honor the presence of an elder, and fear your God. I am the Lord.

33When a foreigner resides with you in your land, you must not oppress him.

34The foreigner who resides with you must be to you like a native citizen among you; so you must love him as yourself, because you were foreigners in the land of Egypt. I am the Lord your God.

35You must not do injustice in the regulation of measures, whether of length, weight, or volume.

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

37You must be sure to obey all my statutes and regulations. I am the Lord.’”
