SEV Biblia, Chapter 18:17
Mas el primogénito de vaca, y el primogénito de oveja, y el primogénito de cabra, no redimirás; santificados son; la sangre de ellos rociarás sobre el altar, y quemarás la grosura de ellos, ofrenda encendida es para el SEÑOR en olor grato.
John Gill's Bible Commentary
Ver. 17. But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem , etc.] 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).
Matthew Henry Commentary
Verses 8-19 - All believers are spiritual priests, and God has promised to take car 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. Scandalou maintenance makes scandalous ministers. The priests were to be wholl devoted to their ministry, not diverted from it, or disturbed in it, by worldly care or business. Also, that they might be examples of livin by faith, not only in God's providence, but in his ordinances. The bes should be offered for the first-fruits unto the Lord. Those who thin to save, by putting God off with the refuse, deceive themselves, for God is not mocked.
