Leviticus 19:34-38

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.

Therefore shall ye observe all my statutes, and all my judgments, and do them: I am the LORD.
