The book of the covenant - See Exodus 20:22 note. The people had to repeat their assent to the book of the covenant before the blood was thrown upon them. Compare 2 Kings 23:2, 2 Kings 23:21; 2 Chronicles 34:30.

The book of the covenant - The writing containing the laws mentioned in the three preceding chapters. As this writing contained the agreement made between God and them, it was called the book of the covenant; but as no covenant was considered to be ratified and binding till a sacrifice had been offered on the occasion, hence the necessity of the sacrifices mentioned here.

Half of the blood being sprinkled on the Altar, and half of it sprinkled on the People, showed that both God and They were mutually bound by this covenant. God was bound to the People to support, defend, and save them; the People were bound to God to fear, love, and serve him. On the ancient method of making covenants, see Clarke on Genesis 6:18 (note); and see Clarke on Genesis 15:18 (note). Thus the blood of the new covenant was necessary to propitiate the throne of justice on the one hand, and to reconcile men to God on the other. On the nature and various kinds of the Jewish offerings, see Clarke's note on Leviticus 7:1, etc.

And he took the book of the covenant,.... Which contained the words of the Lord he is said to write, Exodus 24:4, and consisted both of laws and judgments required of the people, and to which they had given their assent, and promised obedience to; and of promises made by the Lord of sending his angel before them to guide them in the way, and bring them to Canaan, and to drive the Canaanites from thence, and put the Israelites into the possession of it; so that here were promises on both sides, a restipulation of parties, which made a formal covenant:

and read in the audience of the people; he had rehearsed what was contained in it from his memory, by word of mouth, to which they had assented, Exodus 24:3 and having written the same in a book, he read it to them distinctly, that they might the better take notice of the contents of it:

and they said, all that the Lord hath said will we do, and be obedient; which is a repetition and confirmation of what they had before said, and is expressed in stronger terms; so that this was not done suddenly and inconsiderately, and yet they seem not to be so well apprised of their own inability to keep the laws of God, and of the treachery of their own hearts as to their regard to them; see Deuteronomy 5:28.

And he took the book of the covenant, and read in the audience of the people: and they said, All that the LORD hath said will we do, and be obedient.

24:1-8 A solemn covenant was made between God and Israel. Very solemn it was, typifying the covenant of grace between God and believers, through 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's covenants and commands are so just in themselves, and so much for our good, that the more we think of them, and the more plainly and fully 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, and on the people. Neither their persons, their moral obedience, nor religious services, would meet with acceptance from a holy God, except through the shedding and sprinkling' of blood. Also the blessings granted unto them were all of mercy; and the Lord would deal with them in kindness. Thus the sinner, by faith in the blood of Christ, renders willing and acceptable obedience.
