Numbers 18:19 Meaning and Commentary

Numbers 18:19

All the heave offerings of the holy things
All before mentioned, and whatsoever comes under that name:

which the children of Israel offer unto the Lord;
either by his commandment, or of their own freewill;

have I given thee, and thy sons, and thy daughters with thee, by a
statute for ever:
so providing for their maintenance by an irrepealable law as long as their priesthood lasted, even until the Messiah should come:

it [is] a covenant of salt for ever before the Lord unto thee, and thy
seed with thee:
an incorruptible, inviolable, durable covenant, which should last for ever, even until the Gospel dispensation or world to come should take place; and it would remain ever before the Lord in his sight, who would take care it should never be made void, but stand fast with Aaron and his posterity as long as his priesthood endured.

Numbers 18:19 In-Context

17 But the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat, you shall not redeem; they are holy. You shall dash their blood on the altar, and shall turn their fat into smoke as an offering by fire for a pleasing odor to the Lord;

18 but their flesh shall be yours, just as the breast that is elevated and as the right thigh are yours.

19 All the holy offerings that the Israelites present to the Lord I have given to you, together with your sons and daughters, as a perpetual due; it is a covenant of salt forever before the Lord for you and your descendants as well.

20 Then the Lord said to Aaron: You shall have no allotment in their land, nor shall you have any share among them; I am your share and your possession among the Israelites.

21 To the Levites I have given every tithe in Israel for a possession in return for the service that they perform, the service in the tent of meeting.
