15. And Moses went up upon 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 to Moses from 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 ascended the mount: and Moses was on the mount forty days and forty nights.
