Exodus 19:22-24

Young's Literal Translation

²² and also the priests who are coming nigh unto Jehovah do sanctify themselves, lest Jehovah break forth on them.'

²³ And Moses saith unto Jehovah, `The people [is] unable to come up unto mount Sinai, for Thou -- Thou hast protested to us, saying, Make a border [for] the mount, then thou hast sanctified it.'

²⁴ And Jehovah saith unto him, `Go, descend, then thou hast come up, thou, and Aaron with thee; and the priests and the people do not break through, to come up unto Jehovah, lest He break forth upon them.'
