Numbers 18:19

19 all the heave-offerings of the holy things which the sons of Israel lift up to Jehovah I have given to thee and to thy sons, and to thy daughters with thee, by a statute age-during, a covenant of salt, age-during it [is] before Jehovah, to thee and to thy seed with thee.'

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 `Only, the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou dost not ransom, holy they [are]: their blood thou dost sprinkle on the altar, and of their fat thou makest perfume, a fire-offering of sweet fragrance to Jehovah,

18 and their flesh is thine, as the breast of the wave-offering, and as the right leg, it is thine;

19 all the heave-offerings of the holy things which the sons of Israel lift up to Jehovah I have given to thee and to thy sons, and to thy daughters with thee, by a statute age-during, a covenant of salt, age-during it [is] before Jehovah, to thee and to thy seed with thee.'

20 And Jehovah saith unto Aaron, `In their land thou dost not inherit, and a portion thou hast not in their midst: I [am] thy portion, and thine inheritance in the midst of the sons of Israel;

21 and to the sons of Levi, lo, I have given all the tenth in Israel for inheritance in exchange for their service which they are serving -- the service of the tent of meeting.
