Exodus 24:16-18 Easy-to-Read Version (ERV)
16 The Glory of the Lord came down on Mount Sinai. The cloud covered the mountain for six days. On the seventh day, the Lord spoke to Moses from the cloud. 17 The Israelites could see the Glory of the Lord. It was like a fire burning on top of the mountain.
18 Then Moses went higher up the mountain into the cloud. He was on the mountain for 40 days and 40 nights.
