Leviticus 19:33-37

³³And if there should come to you a stranger in your land, ye shall not afflict him.

³⁴The stranger that comes to you shall be among you as the native, and thou shalt love him as thyself; for ye were strangers in the land of Egypt: I am the Lord your God.

³⁵Ye shall not act unrighteously in judgment, in measures and weights and scales.

³⁶There shall be among you just balances and just weights and a just liquid measure. I am the Lord your God, who brought you out of the land of Egypt.

³⁷And ye shall keep all my law and all my ordinances, and ye shall do them: I am the Lord your God.
