Numbers 15:13-16

13All native-born Israelites must do it this way when they bring an offering by fire, a soothing aroma to the Lord.

14“Suppose foreigners are visiting you or living among you in future generations. If they bring an offering by fire, a soothing aroma to the Lord, they must do as you do.

15There is one law for the whole assembly: for you and foreigners who are living with you. It is a permanent law for future generations. As far as the Lord is concerned, you and foreigners are the same.

16The instructions and rules are the same for you as well as foreigners who are living with you.”
