15 Everything that openeth the womb, of all flesh which they offer unto Jehovah, both of man and beast shall be thine: nevertheless the first-born of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.
16 And those that are to be redeemed of them from a month old shalt thou redeem, according to thine estimation, for the money of five shekels, after the shekel of the sanctuary (the same 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 savor unto Jehovah.

Commentary on Numbers 18 Matthew Henry Commentary
Chapter 18
Aaron being now fully established in the priesthood abundantly to his own satisfaction, and to the satisfaction of the people (which was the good that God brought out of the evil opposition made to him), in this chapter God gives him full instructions concerning his office or rather repeats those which he had before given him. He tells him,
Num 18:1-7
The coherence of this chapter with that foregoing is very observable.
Num 18:8-19
The priest's service is called a warfare; and who goes a warfare at his own charges? As they were well employed, so they were well provided for, and well paid. None shall serve God for nought. All believers are spiritual priests, and God has promised to take care of them; they shall dwell in the land, and verily they shall be fed, and shall not want any good thing. Godliness has the promise of the life that now is. And from this plentiful provision here made for the priests the apostle infers that it is the duty of Christian churches to maintain their ministers; those that served at the altar lived upon the altar. So those that preach the gospel should live upon the gospel, and live comfortably, 1 Co. 9:13, 14. Scandalous maintenance makes scandalous ministers. Now observe,
Num 18:20-32
Here is a further account of the provision that was made both for the Levites and for the priests, out of the country.
