Numbers 16:22 - Joseph Benson’s Commentary on the Old and New Testaments

The God of the spirits of all flesh 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 mayest justly destroy this people, so thou canst preserve whom thou pleasest; the Father of spirits, the souls.
