Exodus 19:18-20

BBE(i) 18 And all the mountain of Sinai was smoking, for the Lord had come down on it in fire: and the smoke of it went up like the smoke of a great burning; and all the mountain was shaking. 19 And when the sound of the horn became louder and louder, Moses' words were answered by the voice of God. 20 Then the Lord came down on to Mount Sinai, to the top of the mountain, and the Lord sent for Moses to come up to the top of the mountain, and Moses went up.
