Exodus 19:18-20 Expanded Bible (EXB)
18 Mount Sinai was covered with smoke, because the Lord came down on it in fire. The smoke rose from the mountain like smoke from a ·furnace [kiln], and the whole mountain ·shook wildly [trembled]. 19 The ·sound [blast] from the ·trumpet [ram’s horn] became louder. Then Moses spoke, and ·the voice of [or in thunder] God answered him.
20 When the Lord came down on top of Mount Sinai, he ·called [invited] Moses to come up to the top of the mountain, and Moses went up.
