Numbers 18:19

19 I have given to thee, and to thy sons and thy daughters, by everlasting right, all the first fruits of the saintuary, which the sons of Israel offer to the Lord; it is (an) everlasting covenant of salt before the Lord, to thee, and to thy sons (with thee, and with thy sons).

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.

(But thou shalt not allow the first-born of an ox, or of a sheep, or of a goat, to be bought back, for they be holy to the Lord; thou must throw their blood against the altar, and thou shalt burn their inner fatness to make the sweetest aroma to the Lord.)

18 Soothly the flesh shall fall into thine use, as the breast hallowed and the right shoulder, shall be thine. (But their flesh shall be for thy use, like the breast for the special gift, and the right shoulder, be for thee.)

19 I have given to thee, and to thy sons and thy daughters, by everlasting right, all the first fruits of the saintuary, which the sons of Israel offer to the Lord; it is (an) everlasting covenant of salt before the Lord, to thee, and to thy sons (with thee, and with thy sons).

20 And the Lord said to Aaron, Ye shall not wield anything of heritage in the land of Israel, neither ye shall have part among them; I am thy part and thine heritage, in the midst of the sons of Israel. (And the Lord said to Aaron, Ye shall not possess any inheritance in the land of Israel, nor shall ye have any portion among them; for I am thy portion, and thy inheritance, among the Israelites.)

21 Soothly, I gave to the sons of Levi all the tithes of Israel into possession, for the service by which they serve me in the tabernacle of [the] bond of peace; (Truly, I have given to the sons of Levi all of the tithes of Israel for a possession, for the service which they do in the Tabernacle of the Covenant, that is, the Tabernacle of the Witnessing;)
