By reason of the anointing - See Leviticus 7:35.

And the Lord spake unto Aaron,.... Having pointed out to him the duty of his office, he now informs him of the perquisites of it; or having told him what was his work, now what his wages, or what was his service, and now his maintenance:

behold, I also have given thee the charge of my heave offerings, of all the hallowed things of the children of Israel; such as the heave shoulder and wave breast, and firstfruits, and all other holy things in general, such as were the most holy things; as in Numbers 18:9; and the lighter holy things, as the Jews call them, Numbers 18:11; the charge of these was given to keep for themselves, and for their families:

unto thee have I given them by reason of the anointing: because of his office as a priest, to which he was consecrated by anointing:

and to thy sons by an ordinance for ever; see Leviticus 7:34.

The Revenues of the Priests. - These are summed up in Numbers 18:8 in these words, "I give thee the keeping of My heave-offerings in all holy gifts for a portion, as an eternal statute." The notion of משׁמרת, keeping, as in Exodus 12:6; Exodus 16:23, Exodus 16:32, is defined in the second parallel clause as משׁחה, a portion (see at Leviticus 7:35). The priests were to keep all the heave-offerings, as the portion which belonged to them, out of the sacrificial gifts that the children of Israel offered to the Lord. תּרוּמת, heave-offerings (see at Exodus 25:2, and Leviticus 2:9), is used here in the broadest sense, as including all the holy gifts (kodashim, see Leviticus 21:22) which the Israelites lifted off from their possessions and presented to the Lord (as in Numbers 5:9). Among these, for example, were, first of all, the most holy gifts in the meat-offerings, sin-offerings, and trespass-offerings (Numbers 18:9, Numbers 18:10; see at Leviticus 2:3). The burnt-offerings are not mentioned, because the whole of the flesh of these was burned upon the altar, and the skin alone fell to the portion of the priest (Leviticus 7:8). "From the fire," sc., of the altar. אשׁ, fire, is equivalent to אשּׁה ot , firing (see Leviticus 1:9). These gifts they were to eat, as most holy, in a most holy place, i.e., in the court of the tabernacle (see Leviticus 6:9, Leviticus 6:19; Leviticus 7:6), which is called "most holy" here, to lay a stronger emphasis upon the precept. In the second place, these gifts included also "the holy gifts;" viz., (a) (Numbers 18:11) the heave-offering of their gifts in all wave-offerings (tenuphoth), i.e., the wave-breast and heave-leg of the peace-offerings, and whatever else was waved in connection with the sacrifices (see at Leviticus 7:33): these might be eaten by both the male and female members of the priestly families, provided they were legally clean (Leviticus 22:3.); (b) (Numbers 18:12) the gifts of first-fruits: "all the fat (i.e., the best, as in Genesis 45:18) of oil, new wine, and corn," viz., ראשׁיתם, "the first of them," the בּכּוּרים, "the first-grown fruits" of the land, and that of all the fruit of the ground (Deuteronomy 26:2, Deuteronomy 26:10; Proverbs 3:9; Ezekiel 44:30), corn, wine, oil, honey, and tree-fruit (Deuteronomy 8:8, compared with Leviticus 19:23-24), which were offered, according to 2 Chronicles 31:5; Nehemiah 10:36, Nehemiah 10:38, Tob. 1:6, as first-fruits every year (see Mishnah, Bikkur, i. 3, 10, where the first-fruits are specified according to the productions mentioned in Deuteronomy 8:8; the law prescribed nothing in relation to the quantity of the different first-fruits, but left this entirely to the offerer himself); (c) (Numbers 18:14) everything placed under a ban (see at Leviticus 27:28); and (d) (Numbers 18:15-18) the first-born of man and beast. The first-born of men and of unclean beasts were redeemed according to Numbers 3:47; Exodus 13:12-13, and Leviticus 27:6, Leviticus 27:27; but such as were fit for sacrifice were actually offered, the blood being swung against the altar, and the fat portions burned upon it, whilst the whole of the flesh fell to the portion of the priests. So far as the redemption of human beings was concerned (Numbers 18:16), they were "to redeem from the monthly child," i.e., the first-born child as soon as it was a month old.

And the LORD spake unto Aaron, Behold, I also have given thee the charge of mine heave {d} offerings of all the hallowed things of the children of Israel; unto thee have I given them by reason of the anointing, and to thy sons, by an ordinance for ever.

(d) As the first fruit, first born, and the tithes.

18:8 I have given them - Not only the charge, but the use of them for thyself and family. By reason of the anointing - That is, because thou art priest, and art to devote thyself wholly to my service.

Nu 18:8-20. The Priests' Portion.

8-13. the Lord spake unto Aaron, Behold, I also have given thee the charge of my heave offerings-A recapitulation is made in this passage of certain perquisites specially appropriated to the maintenance of the priests. They were parts of the votive and freewill offerings, including both meat and bread, wine and oil, and the first-fruits, which formed a large and valuable item.

18:8-19 All believers are spiritual priests, and God has promised to take care of them. Godliness has the promise of the life that now is. And from the provision here made for the priests, the apostle shows that it is the duty of christian churches to maintain their ministers. Scandalous maintenance makes scandalous ministers. The priests were to be wholly devoted to their ministry, not diverted from it, or disturbed in it, by worldly care or business. Also, that they might be examples of living by faith, not only in God's providence, but in his ordinances. The best should be offered for the first-fruits unto the Lord. Those who think to save, by putting God off with the refuse, deceive themselves, for God is not mocked.
