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 firstling of a cow, or the firstling of a sheep, or the firstling of a goat thou shalt not redeem. They are holy. Thou shalt sprinkle their blood upon the altar, and shalt burn their fat for an offering made by fire for a sweet savor unto the LORD.

18 And the flesh of them shall be thine, as the wave breast and as the right shoulder are thine.

19 All the heave offerings of the holy things, which the children of Israel offer unto the LORD, have I given thee, and thy sons and thy daughters with thee, by a statute for ever. It is a covenant of salt for ever before the LORD unto thee and to thy seed with thee."

20 And the LORD spoke unto Aaron, "Thou shalt have no inheritance in their land, neither shalt thou have any part among them: I am thy part and thine inheritance among the children of Israel.

21 And behold, I have given the children of Levi all the tenth in Israel for an inheritance for their service which they serve, even the service of the tabernacle of the congregation.
