14After Moses had gone down the mountain to the people, he consecrated them, and they washed their clothes.
15Then he said to the people, “Prepare yourselves for the third day. Abstain from sexual relations.” 16On the morning of the third day there was thunder and lightning, with a thick cloud over the mountain, and a very loud trumpet blast. Everyone in the camp trembled. 17Then Moses led the people out of the camp to meet with God, and they stood at the foot of the mountain.
