Numbers 16:22 - Wesley's Explanatory Notes

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.
