Leviticus 19:32-36

Thou shalt rise up before the hoary head, and honour the face of the old man, and fear thy God: I am the LORD.

And if a stranger sojourn with thee in your land, ye shall not vex him.

But the stranger that dwelleth with you shall be unto you as one born among you, and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I am the LORD your God.

Ye shall do no unrighteousness in judgment, in meteyard, in weight, or in measure.

Just balances, just weights, a just ephah, and a just hin, shall ye have: I am the LORD your God, which brought you out of the land of Egypt.
