Numbers 15:14-16

¹⁴And if a man from another country or any other person living among you, through all your generations, has the desire to give an offering made by fire of a sweet smell to the Lord, let him do as you do.

¹⁵There is to be one law for you and for the man of another country living with you, one law for ever from generation to generation; as you are, so is he to be before the Lord.

¹⁶The law and the rule are to be the same for you and for those from other lands living with you.
