Adam Clarke's Bible Commentary Verse 5. He sent young men] Stout, able, reputable young men, chosen out of the different tribes, for the purpose of killing, flaying, and offering the oxen mentioned here.
Burnt-offerings] They generally consisted of sheep and goats, Lev. i. 10. These were wholly consumed by fire.
Peace-offerings] Bullocks or goats; see Heb. ix. 19. The blood of these was poured out before the Lord, and then the priests and people might feast on the flesh.
Matthew Henry Commentary
Verses 1-8 - A solemn covenant was made between God and Israel. Very solemn it was typifying the covenant of grace between God and believers, throug Christ. As soon as God separated to himself a peculiar people, he governed them by a written word, as he has done ever since. God' covenants and commands are so just in themselves, and so much for ou good, that the more we think of them, and the more plainly and full they are set before us, the more reason we may see to comply with them The blood of the sacrifice was sprinkled on the altar, on the book, an on the people. Neither their persons, their moral obedience, no religious services, would meet with acceptance from a holy God, excep through the shedding and sprinkling' of blood. Also the blessing granted unto them were all of mercy; and the Lord would deal with the in kindness. Thus the sinner, by faith in the blood of Christ, render willing and acceptable obedience. (Ex 24:9-11)
