On the third day in the morning there was thunder and lightning and a dense cloud on the mountain, and the sound of a very loud horn; all the people who were in the camp trembled.
The Lord said to Moses, “I am going to come to you in a dense cloud, so that the people may hear when I speak with you and so that they will always believe in you.” And Moses told the words of the people to the Lord.
While he was still speaking, a bright cloud overshadowed them, and a voice from the cloud said, “This is my one dear Son, in whom I take great delight. Listen to him!”
