“And the LORD spake unto Moses and unto Aaron, saying,”
King James Version (KJV)
16:18 Fire - Taken from the altar which stood in that place, for Aaron might not use other fire. And it is likely the rememberance of the death of Nadab and Abihu deterred them from offering any strange fire.
16:19 Against them - That they might be witnesses of the event, and, upon their success, which they doubted not of, might fall upon Moses and Aaron. And it seems by this that the people were generally incensed against Moses, and inclined to Korah's side. The glory appeared - In the cloud, which then shone with greater brightness and majesty, as a token of God's approach and presence.
16:22 The spirits - And this is no empty title here, but very emphatical. Thou art the maker of spirits, destroy not thy own workmanship! O thou who art the preserver of men, and of their spirits, the Lord of spirits, #Job 12:10|, who as thou mayst justly destroy this people, so thou canst preserve whom thou pleasest: the father of spirits, the souls. Deal mercifully with thy own children: the searcher of spirits, thou canst distinguish between those who have maliciously railed this tumult, and those whose ignorance and simple credulity hath made them a prey to crafty seducers. Of all flesh - Of all mankind: the word flesh is often put for men. One man - Korah, the ringleader of this sedition.
