Numbers 15:14-15

14And if a stranger sojourn with you, or whoever be among you throughout your generations, and will offer an offering by fire of a sweet odour to Jehovah, — as ye do, so shall he do.

15As to the congregation, there shall be one statute for you, and for the stranger that sojourneth with you, an everlasting statute throughout your generations: as ye are, so shall the stranger be, before Jehovah.
