Exodus 19:14-16

New American Standard Bible

¹⁴ So Moses went down from the mountain to the people and consecrated the people, and they washed their garments. ¹⁵ He also said to the people, “Be ready for the third day; do not go near a woman.”

^16 (A)So it came about on the third day, when it was morning, that there were ^[a]thunder and lightning flashes and a thick cloud over the mountain and a very loud trumpet sound, so that all the people who were in the camp trembled.
