Exodus 19
18 Ref Mount Sinai, the whole of it, smoked, because Yahweh descended on it in fire; and its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly.
19 Ref When the sound of the trumpet grew louder and louder, Moses spoke, and God answered him by a voice.
20 Ref Yahweh came down on Mount Sinai, to the top of the mountain. Yahweh called Moses to the top of the mountain, and Moses went up.
