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, wait here for us until we come again unto you; and, behold, Aaron and Hur are with you; if anyone has any matters to settle, let him come unto them.
15 Then 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 for 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 sons of Israel.
18 And Moses entered into the midst of the cloud and went up into the mount, and Moses was in the mount forty days and forty nights.
