14 “Everything devoted in Israel shall be yours. 15 Everything that opens the womb, of all flesh which they offer to Yahweh, both of man and animal shall be yours: nevertheless you shall surely redeem the firstborn of man, and you shall redeem the firstborn of unclean animals. 16 You shall redeem those who are to be redeemed of them from a month old, according to your estimation, for five shekels of money, after the shekel of the sanctuary (the same is twenty gerahs). 17 “But you shall not redeem the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat. They are holy. You shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a pleasant aroma to Yahweh. 18 Their flesh shall be yours, as the wave offering breast and as the right thigh, it shall be yours. 19 All the wave offerings of the holy things, which the children of Israel offer to Yahweh, have I given you, and your sons and your daughters with you, as a portion forever: it is a covenant of salt forever before Yahweh to you and to your seed with you.”
Matthew Henry's Commentary on Numbers 18:14-19
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.
