Numbers 15:14-15

14Whenever an outsider resides with you, or whoever is among you for your generations to come, and he is to present a fire offering as a fragrant aroma to Adonai, as you do, he must do exactly the same as you are doing.

15“The community will have the same rule for you as well as for the resident outsider. It will be a lasting statute throughout your generations. As for you, so for the outsider will it be before Adonai.
