Exodus 19:20-22

New American Standard Bible

²⁰ Then ^(A)the Lord came down on Mount Sinai, to the top of the mountain; and the Lord called Moses to the top of the mountain, and Moses went up. ²¹ Then the Lord spoke to Moses: “Go down, ^[a]warn the people, so that ^(B)they do not break through to the Lord to stare, and many of them ^[b]perish. ²² Also have the ^(C)priests who approach the Lord consecrate themselves, or else the Lord will break out against them.”
