The people were out of Egypt. They’d gone through the wilderness. Now, they had arrived at the mountain of God.

“There were thunderings and lightnings, and a thick cloud on the mountain; and the sound of the trumpet was very loud, so that all the people who were in the camp trembled. And Moses brought the people out of the camp to meet with God, and they stood at the foot of the mountain.” – Exodus 19:16-17
