Numbers 18:17 Meaning and Commentary

Numbers 18:17

But the firstling of a cow, or the firstling of a sheep, or
the firstling of a goat, thou shalt not redeem
That is, shalt not take the redemption price for them, but the creatures themselves; which they, the priests, were to take for their own use:

they [are] holy;
separated to the Lord, and therefore not to be used in common by men, but were sacred to the Lord, or became the property of his priests; see ( Deuteronomy 15:19 ) ; how they were to be made use of follows:

thou shalt sprinkle their blood upon the altar;
for they were to be sacrificed, and their blood used as in other sacrifices:

and shalt burn their fat [for] an offering made by fire; for a sweet
savour unto the Lord;
as the fat of other sacrifices was, and particularly of the peace offerings, which were wholly eaten otherwise, ( Leviticus 7:31 ) .

Numbers 18:17 In-Context

15 Everything that opens the womb of all flesh, whether man or beast, which they offer to the LORD, shall be yours; nevertheless the first-born of man you shall redeem, and the firstling of unclean beasts you shall redeem.

16 And their redemption price (at a month old you shall redeem them) you shall fix at five shekels in silver, according to 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, you shall not redeem; they are holy. You shall sprinkle their blood upon the altar, and shall burn their fat as an offering by fire, a pleasing odor to the LORD;

18 but their flesh shall be yours, as the breast that is waved and as the right thigh are yours.

19 All the holy offerings which the people of Israel present to the LORD I give to you, and to your sons and daughters with you, as a perpetual due; it is a covenant of salt for ever before the LORD for you and for your offspring with you."
