Leviticus 19:33-35

New Revised Standard Version Catholic Edition

³³ When an alien resides with you in your land, you shall not oppress the alien. ³⁴ The alien who resides with you shall be to you as the citizen among you; you shall love the alien as yourself, for you were aliens in the land of Egypt: I am the Lord your God.

³⁵ You shall not cheat in measuring length, weight, or quantity.
