Exodus 19:15-17

Revised Standard Version

¹⁵ And he said to the people, “Be ready by the third day; do not go near a woman.”

¹⁶ On the morning of the third day there were thunders and lightnings, and a thick cloud upon the mountain, and a very loud trumpet blast, so that all the people who were in the camp trembled. ¹⁷ Then Moses brought the people out of the camp to meet God; and they took their stand at the foot of the mountain.
