Then followed the ratification of the covenant. An altar was built at the foot of the mountain, and beside it twelve pillars were set up, “according to the twelve tribes of Israel,”(Exodus 24:4) as a testimony to their acceptance of the covenant. Sacrifices were then presented by young men chosen for the service. (PP 312.1) MC VC

Having sprinkled the altar with the blood of the offerings, Moses “took the book of the covenant, and read in the audience of the people.” Exodus 24:7. Thus the conditions of the covenant were solemnly repeated, and all were at liberty to choose whether or not they would comply with them. They had at the first promised to obey the voice of God; but they had since heard His law proclaimed; and its principles had been particularized, that they might know how much this covenant involved. Again the people answered with one accord, “All that the Lord hath said will we do, and be obedient.” “When Moses had spoken every precept to all the people according to the law, he took the blood, ... and sprinkled both the book and all the people, saying, This is the blood of the testament which God hath enjoined unto you.” Hebrews 9:19, 20.

Arrangements were now to be made for the full establishment of the chosen nation under Jehovah as their king. Moses had received the command, “Come up unto the Lord, thou, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel; and worship ye afar off. And Moses alone shall come near the Lord.” Exodus 24:1, 2. While the people worshiped at its foot, these chosen men were called up into the mount. The seventy elders were to assist Moses in the government of Israel, and God put upon them His Spirit, and honored them with a view of His power and greatness. “And they saw the God of Israel: and there was under His feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness.” Exodus 24:10. They did not behold the Deity, but they saw the glory of His presence. Before this they could not have endured such a scene; but the exhibition of God’s power had awed them to repentance; they had been contemplating His glory, purity, and mercy, until they could approach nearer to Him who was the subject of their meditations.
