And Moses alone shall come near the LORD: but they shall not come nigh; neither shall the people go up with him.

Wesley's Notes

24:2 And Moses alone shall come near - Being therein a type of Christ, who as the high priest entered alone into the most holy place. In the following verse s we have the solemn covenant made between God and Israel and the exchanging of the ratifications: typifying the covenant of grace between God and believers through Christ.

Matthew Henry's Concise Commentary

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.
