The covenant confirmed

1And he said to Moses, “Come up to the LORD, you and Aaron, Nadab, and Abi'hu, and seventy of the elders of Israel, and worship afar off. 2Moses alone shall come near to the LORD; but the others shall not come near, and the people shall not come up with him.”

3Moses came and told the people all the words of the LORD and all the ordinances; and all the people answered with one voice, and said, “All the words which the LORD has spoken we will do.” 4And Moses wrote all the words of the LORD. And he rose early in the morning, and built an altar at the foot of the mountain, and twelve pillars, according to the twelve tribes of Israel. 5And he sent young men of the people of Israel, who offered burnt offerings and sacrificed peace offerings of oxen to the LORD. 6And Moses took half of the blood and put it in basins, and half of the blood he threw against the altar. 7Then he took the book of the covenant, and read it in the hearing of the people; and they said, “All that the LORD has spoken we will do, and we will be obedient.” 824.8: Mt 26.28; Mk 14.24; Lk 22.20; 1 Cor 11.25; Heb 9.20; 10.29.And Moses took the blood and threw it upon the people, and said, “Behold the blood of the covenant which the LORD has made with you in accordance with all these words.”

9Then Moses and Aaron, Nadab, and Abi'hu, and seventy of the elders of Israel went up, 10and they saw the God of Israel; and there was under his feet as it were a pavement of sapphire stone, like the very heaven for clearness. 11And he did not lay his hand on the chief men of the people of Israel; they beheld God, and ate and drank.

1224.12: 2 Cor 3.3.The LORD said to Moses, “Come up to me on the mountain, and wait there; and I will give you the tables of stone, with the law and the commandment, which I have written for their instruction.” 13So Moses rose with his servant Joshua, and Moses went up into the mountain of God. 14And he said to the elders, “Tarry here for us, until we come to you again; and, behold, Aaron and Hur are with you; whoever has a cause, let him go to them.”

15Then Moses went up on the mountain, and the cloud covered the mountain. 16The glory of the LORD settled on Mount Sinai, and the cloud covered it six days; and on the seventh day he called to Moses out of the midst of the cloud. 17Now the appearance of the glory of the LORD was like a devouring fire on the top of the mountain in the sight of the people of Israel. 18And Moses entered the cloud, and went up on the mountain. And Moses was on the mountain forty days and forty nights.
