Numbers 15:13-16

13All that are homeborn shall do these things after this manner, in offering an offering made by fire, of a sweet savour unto the LORD.

14And if a stranger sojourn with you, or whosoever be among you throughout your generations, and will offer an offering made by fire, of a sweet savour unto the LORD; as ye do, so he shall do.

15For the assembly, there shall be one statute for you, and for the stranger that sojourneth with you, a statute for ever throughout your generations: as ye are, so shall the stranger be before the LORD.

16One law and one ordinance shall be for you, and for the stranger that sojourneth with you.
