Exodus 19:15-17

New Revised Standard Version Catholic Edition

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

¹⁶ On the morning of the third day there was thunder and lightning, as well as a thick cloud on the mountain, and a blast of a trumpet so loud that all the people who were in the camp trembled. ¹⁷ Moses brought the people out of the camp to meet God. They took their stand at the foot of the mountain.
