Exodus 24:15-17

Darby Translation

¹⁵ And Moses went up to the mountain, and the cloud covered the mountain.

¹⁶ And the glory of Jehovah abode on mount Sinai, and the cloud covered it six days; and on the seventh day he called to Moses out of the midst of the cloud.

¹⁷ And the appearance of the glory of Jehovah was like a consuming fire on the top of the mountain, before the eyes of the children of Israel.
