Leviticus 19:32-37

Thou shalt rise up before the hoary head, and honor the face of the old man, and thou shalt fear thy God: I am Jehovah. And if a stranger sojourn with thee in your land, ye shall not do him wrong. The stranger that sojourneth with you shall be unto you as the home-born among you, and thou shalt love him as thyself; for ye were sojourners in the land of Egypt: I am Jehovah your God. Ye shall do no unrighteousness in judgment, in measures of length, of weight, or of quantity. Just balances, just weights, a just ephah, and a just hin, shall ye have: I am Jehovah your God, who brought you out of the land of Egypt. And ye shall observe all my statutes, and all mine ordinances, and do them: I am Jehovah.
