Exodus 19:20-22

New King James Version

²⁰ Then the Lord came down upon Mount Sinai, on the top of the mountain. And the Lord called Moses to the top of the mountain, and Moses went up.

²¹ And the Lord said to Moses, “Go down and warn the people, lest they break through ^(A)to gaze at the Lord, and many of them perish. ²² Also let the ^(B)priests who come near the Lord ^(C)consecrate themselves, lest the Lord ^(D)break out against them.”
