Job 2:6

“And the Lord said unto Satan, behold, he [is] in thine hand, etc.] Well may a behold be prefixed to this, it being matter of wonder and astonishment that a saint and servant of God should be permitted to be in the hand of Satan; which yet must not be so understood; as if he was off of, and no more upon the heart of God; or as if he was out of the hands of God, and out of the hands of Christ; or as if he was become Satan’s property, and a child of his; for neither of these can be true of a good man: nothing can separate him from the love of God; not Satan and all his principalities and powers; nor can men or devils pluck them out of his hands, nor out of the hands of his son; nor can those…”

“but save--rather, "only spare his life." Satan shows his ingenuity in inflicting pain, and also his knowledge of what man's body can bear without vital injury.”

“Behold, he is in thine hand - He is at thy disposal; see Job 1:12, Margin. But save his life - Margin, “only.” This was to be the only limitation. It would seem that he had the power to make any selection of disease, and to afflict him in any manner, provided it did not terminate fatally. The keen sorrows which Job afterward endured showed the malignancy of the tempter; evinced his ingenuity in inflicting pain, and his knowledge of what thc human frame could be made to bear. return to 'Top of Page'”

“In thine hand - If God did not chain up the roaring lion, how soon would he devour us! As far as he permits the wrath of Satan and wicked men, to proceed against his people, he will make it turn to his praise and theirs, and the remainder thereof he will restrain. Job, in being thus maligned of Satan, was a type of Christ. He had permission to bruise his heel, to touch his bone and his flesh; yea, and his life also; because by dying he was to do what Job could not do, to destroy him that had the power of death. Job 2:7”

“2:6 spare (literally guard/watch over): God ironically made Satan responsible for guarding Job’s life (cp. 10:13-14; 13:27; 33:11).”

“Behold: Job 1:12 but: or, only save: Job 38:10, Job 38:11; Psa 65:7; Luk 8:29-33, Luk 22:31, Luk 22:32; Co1 10:13; Rev 2:10; Rev 20:1, Rev 20:2, Rev 20:7 his life: By naphsho, "his soul," Maimonides understands "his mind," or intellectual powers. Job 2:7”

“The Grant of New Power: 6 And Jehovah said to Satan, Behold, he is in thy hand; only take care of his life. Job has not forfeited his life; permission is given to place it in extreme peril, and nothing more, in order to see whether or not, in the face of death, he will deny the God who has decreed such heavy affliction for him. נפשׁ does not signify the same as חיּים; it is the soul producing the spirit-life of man. We must, however, translate "life," because we do not use "soul" in the sense of ψυχή, anima. Job 2:7”
