Exodus 24:16-18

Brenton(i) 16 And the glory of God came down upon the mount Sina, and the cloud covered it six days; and the Lord called Moses on the seventh day out of the midst of the cloud. 17 And the appearance of the glory of the Lord was as burning fire on the top of the mountain, before the children of Israel. 18 And Moses went into the midst of the cloud, and went up to the mountain, and was there in the mountain forty days and forty nights.
