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. (PP 312.2) MC VC

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. (PP 312.3) MC VC

Another compact—called in Scripture the “old” covenant—was formed between God and Israel at Sinai, and was then ratified by the blood of a sacrifice. The Abrahamic covenant was ratified by the blood of Christ, and it is called the “second,” or “new,” covenant, because the blood by which it was sealed was shed after the blood of the first covenant. That the new covenant was valid in the days of Abraham is evident from the fact that it was then confirmed both by the promise and by the oath of God—the “two immutable things, in which it was impossible for God to lie.” Hebrews 6:18. (PP 371.1) MC VC

But if the Abrahamic covenant contained the promise of redemption, why was another covenant formed at Sinai? In their bondage the people had to a great extent lost the knowledge of God and of the principles of the Abrahamic covenant. In delivering them from Egypt, God sought to reveal to them His power and His mercy, that they might be led to love and trust Him. He brought them down to the Red Sea—where, pursued by the Egyptians, escape seemed impossible—that they might realize their utter helplessness, their need of divine aid; and then He wrought deliverance for them. Thus they were filled with love and gratitude to God and with confidence in His power to help them. He had bound them to Himself as their deliverer from temporal bondage. (PP 371.2) MC VC

But there was a still greater truth to be impressed upon their minds. Living in the midst of idolatry and corruption, they had no true conception of the holiness of God, of the exceeding sinfulness of their own hearts, their utter inability, in themselves, to render obedience to God’s law, and their need of a Saviour. All this they must be taught. (PP 371.3) MC VC

God brought them to Sinai; He manifested His glory; He gave them His law, with the promise of great blessings on condition of obedience: “If ye will obey My voice indeed, and keep My covenant, then ... ye shall be unto Me a kingdom of priests, and an holy nation.” Exodus 19:5, 6. The people did not realize the sinfulness of their own hearts, and that without Christ it was impossible for them to keep God’s law; and they readily entered into covenant with God. Feeling that they were able to establish their own righteousness, they declared, “All that the Lord hath said will we do, and be obedient.” Exodus 24:7. They had witnessed the proclamation of the law in awful majesty, and had trembled with terror before the mount; and yet only a few weeks passed before they broke their covenant with God, and bowed down to worship a graven image. They could not hope for the favor of God through a covenant which they had broken; and now, seeing their sinfulness and their need of pardon, they were brought to feel their need of the Saviour revealed in the Abrahamic covenant and shadowed forth in the sacrificial offerings. Now by faith and love they were bound to God as their deliverer from the bondage of sin. Now they were prepared to appreciate the blessings of the new covenant. (PP 371.4) MC VC
