Exodus 19:22-24

Darby Translation

²² And the priests also, who come near to Jehovah, shall hallow themselves, lest Jehovah break forth on them.

²³ And Moses said to Jehovah, The people cannot come up to mount Sinai; for thou hast testified to us, saying, Set bounds about the mountain, and hallow it.

²⁴ And Jehovah said to him, Go, descend, and thou shalt come up, thou, and Aaron with thee; but the priests and the people shall not break through to go up to Jehovah, lest he break forth on them.
