Exodus 19:15-17

Darby Translation

¹⁵ And he said to the people, Be ready for the third day; do not come near [your] wives.

¹⁶ And it came to pass on the third day, when it was morning, that there were thunders and lightnings and a heavy cloud on the mountain, and the sound of the trumpet exceeding loud; and the whole people that was in the camp trembled.

¹⁷ And Moses brought the people out of the camp to meet with God; and they stood at the foot of the mountain.
