Exodus 19:22-24

Revised Standard Version

²² And also let the priests who come near to the Lord consecrate themselves, lest the Lord break out upon them.” ²³ And Moses said to the Lord, “The people cannot come up to Mount Sinai; for thou thyself didst charge us, saying, ‘Set bounds about the mountain, and consecrate it.’” ²⁴ And the Lord said to him, “Go down, and come up bringing Aaron with you; but do not let the priests and the people break through to come up to the Lord, lest he break out against them.”
