12: And the LORD said unto Moses, Come up to me into the mount, and be there: and I will give thee tables of stone, and a law, and commandments which I have written; that thou mayest teach them.

13: And Moses rose up, and his minister Joshua: and Moses went up into the mount of God.

14: And he said unto the elders, Tarry ye here for us, until we come again unto you: and, behold, Aaron and Hur are with you: if any man have any matters to do, let him come unto them.

15: And Moses went up into the mount, and a cloud covered the mount.

16: And the glory of the LORD abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud.

17: And the sight of the glory of the LORD was like devouring fire on the top of the mount in the eyes of the children of Israel.

18: And Moses went into the midst of the cloud, and gat him up into the mount: and Moses was in the mount forty days and forty nights.
