Exodus 24:12

9 Then Moses and Aaron, Nadab, and Abihu, and seventy of the chiefs of Israel went up:

10 And they saw the God of Israel; and under his feet there was, as it seemed, a jewelled floor, clear as the heavens.

11 And he put not his hand on the chiefs of the children of Israel: they saw God, and took food and drink.

12 And the Lord said to Moses, Come up to me on the mountain, and take your place there: and I will give you the stones on which I have put in writing the law and the orders, so that you may give the people knowledge of them.

13 Then Moses and Joshua his servant got up; and Moses went up into the mountain of God.

14 And he said to the chiefs, Keep your places here till we come back to you: Aaron and Hur are with you; if anyone has any cause let him go to them.

15 And Moses went up into the mountain, and it was covered by the cloud.
