13 So Moses and his assistant Joshua got up, and Moses went up God’s mountain.
14 Moses had said to the elders, "Wait for us here until we come back to you. Aaron and Hur will be here with you. Whoever has a legal dispute may go to them."
15 Then Moses went up the mountain, and the cloud covered the mountain.
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.
