15. And when Moses was gone up, a cloud covered the mount.
16. And the glory of the Lord dwelt upon Sinai, covering it with a cloud six days: and the seventh day he called him out of the midst of the cloud.
17. And the sight of the glory of the Lord was like a burning fire upon the top of the mount, in the eyes of the children of Israel.
18. And Moses, entering into the midst of the cloud, went up into the mountain: and he was there forty days, and forty nights.
