To bring back his soul from the pit - To keep him from descending to the grave, and to the dark world beneath. He takes these methods of warning people, in order that they may not bring destruction on themselves. See Job 33:18.
To be enlightened with the light of the living - That he may still enjoy life, and not descend to the world of shades.

To bring back his soul from the pit - Nearly a repetition of the promise in Job 33:28.
To be enlightened with the light of the living - An echo of Psalm 56:13 : "Thou hast delivered my soul from death, that I may walk before God in the light of the living;" and probably quoted from it.

To bring back his soul from the pit,.... From the pit of the grave; at the mouth or on the brink of which he seemed to be in the apprehension of his friends, and having the sentence of death in himself; see Psalm 90:3. Or "to turn away" (x), or "stay his soul from the pit", as Mr. Broughton; prevent his going into it by removing his disorder, and restoring him to health, as in the case of Hezekiah, Isaiah 38:17. Or figuratively, from the pit of an unregenerate state, which may be compared to a pit or grave, because in it lie such who are dead in trespasses and sins; and which is a pit of corruption, or a corrupt state: men in it are corrupt and corrupters, corrupt both in principles and practices; and is an impure one, like to mire and clay; and a very uncomfortable one, a pit wherein is no water, no refreshment, no solid peace and comfort. In conversion, which sometimes is brought about by the above means, afflictive providences, as well as by the ministry of the word, souls are brought back from hence; are regenerated, quickened, and raised from the graves of sin, and live spiritually, as they are also secured from going down into the pit of hell and everlasting destruction:
to be enlightened with the light of the living; in a natural sense, to enjoy the light of living men, the light of the sun, and to live in health and prosperity, which is called light in opposition to affliction and adversity, expressed by darkness; see Esther 8:15, Isaiah 8:22. And in a spiritual sense, to live a spiritual life, who before were dead in sin, to live a life of faith on Christ as their righteousness, and to live a life of holiness from him, and in newness of life to his honour and glory; and to have spiritual light into their state by nature, and their recovery and salvation by Christ; to see their need of him, his suitableness, worth, and excellency, and to have a glimpse of eternal glory; as also hereafter to partake both of eternal life and eternal light, called by our Lord "the light of life", John 8:12.
(x) "ut avertat", Beza, Mercerus, Piscator, Michaelis, Schultens.

Referring to Job 33:28 (Psalm 50:13).

To bring - That he may save men from being forever miserable, and make them forever happy. "Lord, what is man, that thou shouldest thus visit him? This should engage us, to comply with God's designs, to work with him for our own good, and not to counter - work him. And this will render those that perish inexcusable, that, so much was done to save them, and they would not he healed." So Mr. Henry. Excellent words! But how much did God do to save them? Did he ever do any thing to save them? Did he ever design to save them? If not, how does that which was never done, no nor designed, "render them inexcusable?"
