Exodus 19:18-20

Lexham English Bible

¹⁸ And Mount Sinai was all wrapped in smoke because Yahweh went down on it in the fire, and its smoke went up like the smoke of a smelting furnace, and the whole mountain trembled greatly. ¹⁹ And the sound of the ram’s horn became louder and louder,^[a] and Moses would speak, and God would answer him with a voice.

²⁰ And Yahweh went down on Mount Sinai, to the top of the mountain, and Yahweh called Moses to the top of the mountain, and Moses went up.
