Of the spirits, i.e. of souls, as the word spirit in Scripture is oft used, as Psa_31:5 77:3 Pro_17:22Ecc_12:7Luk_23:46Act_7:59. And this is no empty title here, but very emphatical and argmmentative, thus, Thou art the Maker of spirits, Zec_12:1, destroy not thy own workmanship, Isa_64:8. 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, Heb_12:9; O deal mercifully with thy own children: the Searcher of spirits, thou canst distinguish between those who have maliciously raised this tumult, and those whose ignorance and simple credulity hath made them a prey to crafty seducers.
Of all flesh, i.e. of all mankind: the word flesh is put for men, as Gen_6:13Job_12:10Isa_40:5,6 Eze 20:48 21:4,5.
One man, to wit, Korah, the ringleader of this sedition.
