15 The first offspring of every womb, both human and animal, that is offered to the Lord is yours. But you must redeem every firstborn son and every firstborn male of unclean animals. 16 When they are a month old, you must redeem them at the redemption price set at five shekels[1] of silver, according to the sanctuary shekel, which weighs twenty gerahs. 17 "But you must not redeem the firstborn of a cow, a sheep or a goat; they are holy. Splash their blood against the altar and burn their fat as a food offering, an aroma pleasing to the Lord.
15 Every thing that openeth the matrix in all flesh, which they bring unto the Lord, whether it be of men or beasts, shall be thine: nevertheless the firstborn of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem. 16 And those that are to be redeemed from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary, which is twenty gerahs. 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 savour unto the Lord.
15 Everything that opens the womb of all flesh, whether man or beast, which they offer to the Lord, shall be yours. Nevertheless, the firstborn of man you shall redeem, and the firstborn of unclean animals you shall redeem. 16 And their redemption price (at a month old you shall redeem them) you shall fix at five shekels
15 Every firstborn that is offered to God, whether animal or person, is yours. Except you don't get the firstborn itself, but its redemption price; firstborn humans and ritually clean animals are bought back and you get the redemption price. 16 When the firstborn is a month old it must be redeemed at the redemption price of five shekels of silver, using the standard of the Sanctuary shekel, which weighs twenty gerahs. 17 "On the other hand, you don't redeem a firstborn ox, sheep, or goat - they are holy. Instead splash their blood on the Altar and burn their fat as a Fire-Gift, a pleasing fragrance to God.
15 Everything that first opens the womb of all flesh, which they bring to the Lord, whether man or beast, shall be yours; nevertheless the firstborn of man you shall surely redeem, and the firstborn of unclean animals you shall redeem. 16 And those redeemed of the devoted things you shall redeem when one month old, according to your valuation, for five shekels of silver, according to the shekel of the sanctuary, which is twenty gerahs. 17 But the firstborn of a cow, the firstborn of a sheep, or the firstborn of a goat you shall not redeem; they are holy. You shall sprinkle their blood on the altar, and burn their fat as an offering made by fire for a sweet aroma to the Lord.
15 "The firstborn of every mother, whether human or animal, that is offered to the Lord will be yours. But you must always redeem your firstborn sons and the firstborn of ceremonially unclean animals. 16 Redeem them when they are one month old. The redemption price is five pieces of silver (as measured by the weight of the sanctuary shekel, which equals twenty gerahs). 17 "However, you may not redeem the firstborn of cattle, sheep, or goats. They are holy and have been set apart for the Lord . Sprinkle their blood on the altar, and burn their fat as a special gift, a pleasing aroma to the Lord .
Matthew Henry's Commentary on Numbers 18:15-17
Commentary on Numbers 18:8-19
(Read Numbers 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.
