Exodus 19:20-22

Authorized (King James) Version

²⁰ And the Lord came down upon mount Sinai, on the top of the mount: and the Lord called Moses up to the top of the mount; and Moses went up. ²¹ And the Lord said unto Moses, Go down, charge the people, lest they break through unto the Lord to gaze, and many of them perish. ²² And let the priests also, which come near to the Lord, sanctify themselves, lest the Lord break forth upon them.
