Exodus 24:15-17

New Revised Standard Version Catholic Edition

¹⁵ Then Moses went up on the mountain, and the cloud covered the mountain. ¹⁶ The glory of the Lord settled on Mount Sinai, and the cloud covered it for six days; on the seventh day he called to Moses out of the cloud. ¹⁷ Now the appearance of the glory of the Lord was like a devouring fire on the top of the mountain in the sight of the people of Israel.
