Leviticus 19:33-37

‘When a stranger resides with you in your land, you shall not oppress or mistreat him. But the stranger who resides with you shall be to you like someone native-born among you; and you shall love him as yourself, for you were strangers in the land of Egypt; I am the LORD your God. ‘You shall do no wrong in judgment, in measurement of weight or quantity. You shall have just and accurate balances, just weights, a just ephah, and a just hin. I am the LORD your God, who brought you out of the land of Egypt. You shall observe and keep all My statutes and all My ordinances and do them. I am the LORD.’ ”
