Exodus 24:16-18 Common English Bible (CEB)
16 The Lord’s glorious presence settled on Mount Sinai, and the cloud covered it for six days. On the seventh day the Lord called to Moses from the cloud. 17 To the Israelites, the Lord’s glorious presence looked like a blazing fire on top of the mountain. 18 Moses entered the cloud and went up the mountain. Moses stayed on the mountain for forty days and forty nights.
