Exodus 24:9–13

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

12 The LORD said to Moses, “Come up to me on the mountain and wait there, that I may give you the tablets of stone, with the law and the commandment, which I have written for their instruction.” 13 So Moses rose with his assistant Joshua, and Moses went up into the mountain of God.
