Exodus 24:13

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.

16 And the glory of the Lord was resting on Mount Sinai, and the cloud was over it for six days; and on the seventh day he said Moses' name out of the cloud.
