Numbers 15:13-16

13Every native Israelite shall do these things in this way, in offering a food offering, with a pleasing aroma to the Lord.

14And if a stranger is sojourning with you, or anyone is living permanently among you, and he wishes to offer a food offering, with a pleasing aroma to the Lord, he shall do as you do.

15For the assembly, there shall be one statute for you and for the stranger who sojourns with you, a statute forever throughout your generations. You and the sojourner shall be alike before the Lord.

16One law and one rule shall be for you and for the stranger who sojourns with you."
