Exodus 19:19-21

Darby Translation

¹⁹ And the sound of the trumpet increased and became exceeding loud; Moses spoke, and God answered him by a voice.

²⁰ And Jehovah came down on mount Sinai, on the top of the mountain; and Jehovah called Moses to the top of the mountain, and Moses went up.

²¹ And Jehovah said to Moses, Go down, testify to the people that they break not through to Jehovah to gaze, and many of them perish.
