Exodus 19:15-17 New Life Version (NLV)
15 He said to the people, “Be ready for the third day. Do not go near a woman.”
16 On the morning of the third day there was thunder and lightning. A cloud covered the mountain, and a very loud horn sounded. All the people among the tents shook with fear. 17 Then Moses brought the people from among the tents to meet God. They stood at the base of the mountain.
