Numbers 18:19-21

¹⁹All the consecrated separations which the sons of Israel set apart before the Lord, I have given to thee and to thy children with thee by an everlasting covenant; an everlasting covenant of salt it is before the Lord, with thee, and thy children with thee.

²⁰And the Lord said to Aharon: In their land thou wilt not have possession, nor will thine be a portion among them; the gifts that I have given thee, they are thy portion and thy inheritance among the children of Israel.

²¹And to the sons of Levi, behold, I have given all the tenths in Israel for a possession, on account of the service with which they serve in the ministry of the tabernacle of ordinance.
