Exodus 24:9-18

Then Moses, Aaron, Nadab, and Abihu, and seventy of the elders of Israel went up [the mountainside], and they saw [a manifestation of] the God of Israel; and under His feet there appeared to be a pavement of sapphire, just as clear as the sky itself. [Ex 33:20-23; Deut 4:12; Ezek 28:14] Yet He did not stretch out His hand against the nobles of the Israelites; and they saw [the manifestation of the presence of] God, and ate and drank. [Ex 19:21] Now the LORD said to Moses, “Come up to Me on the mountain and stay there, and I will give you the stone tablets with the law and the commandments which I have written for their instruction.” [2 Cor 3:2, 3] So Moses arose with Joshua his attendant, and he went up to the mountain of God. And he said to the elders, “Wait here for us until we come back to you. Remember that Aaron and Hur are with you; whoever has a legal matter, let him go to them.” Then Moses went up to the mountain, and the cloud covered the mountain. The glory and brilliance of the LORD rested on Mount Sinai, and the cloud covered it for six days. On the seventh day God called to Moses from the midst of the cloud. In the sight of the Israelites the appearance of the glory and brilliance of the LORD was like consuming fire on the top of the mountain. Moses entered the midst of the cloud and went up the mountain; and he was on the mountain forty days and forty nights.
