Exodus 24:9-13

Then Moses went up with Aaron, Nadab and Abihu, and seventy of the elders of Israel,

and they saw the God of Israel; and under His feet there appeared to be a pavement of sapphire, as clear as the sky itself.

Yet He did not reach out with His hand against the nobles of the sons of Israel; and they saw God, and they ate and drank.

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.”

So Moses got up along with Joshua his servant, and Moses went up to the mountain of God.
