Exodus 19:20-22

New Living Translation

²⁰ The Lord came down on the top of Mount Sinai and called Moses to the top of the mountain. So Moses climbed the mountain.

²¹ Then the Lord told Moses, “Go back down and warn the people not to break through the boundaries to see the Lord, or they will die. ²² Even the priests who regularly come near to the Lord must purify themselves so that the Lord does not break out and destroy them.”
