Numbers 15:13-16

13Everyone who is native-born shall prepare these things in this way when he presents a food offering as a pleasing aroma to the LORD. 14And for the generations to come, if a foreigner residing with you or someone else among you wants to prepare a food offering as a pleasing aroma to the LORD, he is to do exactly as you do. 15The assembly is to have the same statute both for you and for the foreign resident; it is a permanent statute for the generations to come. You and the foreigner shall be the same before the LORD. 16The same law and the same ordinance will apply both to you and to the foreigner residing with you.”
