Exodus 19:21-23

21st Century King James Version

²¹ And the Lord said unto Moses, “Go down. Charge the people, lest they break through to gaze unto the Lord, and many of them perish.

²² And let the priests also, who come near to the Lord, sanctify themselves, lest the Lord break forth upon them.”

²³ And Moses said unto the Lord, “The people cannot come up to Mount Sinai; for Thou charged us, saying, ‘Set bounds about the mount and sanctify it.’”
