1Then He said to Moses, “Come up to the LORD, you and Aaron, Nadab and Abihu and seventy of the elders of Israel, and you shall worship at a distance. 2Moses alone, however, shall come near to the LORD, but they shall not come near, nor shall the people come up with him.”
3Then Moses came and recounted to 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!”
4Moses wrote down all the words of the LORD. Then he arose early in the morning, and built an altar  at the foot of the mountain with twelve pillars for the twelve tribes of Israel. 5He sent young men of the sons of Israel, and they offered burnt offerings and sacrificed young bulls as peace offerings to the LORD. 6Moses took half of the blood and put it in basins, and the other half of the blood he sprinkled on 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!”
9Then Moses went up  with Aaron, Nadab and Abihu, and seventy of the elders of Israel, 10and they saw the God of Israel; and under His feet  there appeared to be a pavement of sapphire,  as clear as the sky itself. 11Yet He did not stretch out His hand against the nobles of the sons of Israel; and they saw God, and they ate and drank.
12Now the LORD said to Moses, “Come up to Me on the mountain and  remain there, and I will give you the stone tablets  with the law and the commandment which I have written for their instruction.”
13So Moses arose  with Joshua his  servant, and Moses went up to the mountain of God. 14But to the elders he said, “Wait here for us until we return to you. And behold, Aaron and Hur are with you; whoever  has a legal matter, let him approach them.”
15Then Moses went up to the mountain, and the cloud covered the mountain. 16The glory of the LORD  rested on Mount Sinai, and the cloud covered it for six days; and on the seventh day He called to Moses from the midst of the cloud. 17And to the eyes of the sons of Israel the appearance of the glory of the LORD was like a consuming fire on the mountain top. 18Moses entered the midst of the cloud  as he went up to the mountain; and Moses was on the mountain forty days and forty nights.
