Exodus 19:20-22

Amplified Bible, Classic Edition

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

²¹ The Lord said to Moses, Go down and warn the people, lest they break through to the Lord to gaze and many of them perish.

²² And also let the priests, who come near to the Lord, sanctify (set apart) themselves [for God], lest the Lord break forth against them.
