24:4 And Moses wrote the words of the Lord - That there might be no mistake; as God dictated them on the mount, where, it is highly probable, God taught him the use of letters. These Moses taught the Israelites, from whom they afterwards travelled to Greece and other nations. As soon as God had separated to himself a peculiar people, he governed them by a written word, as he has done ever since, and will do while the world stands. Pillars according to the number of the tribes - These were to represent the people, the other party to the covenant; and we may suppose they were set up over against the altar, and that Moses as mediator passed to and fro between them. Probably each tribe set up and knew its own pillar, and their elders stood by it. He then appointed sacrifices to be offered upon the altar.
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.
