Job 2:6 - Wesley's Explanatory Notes

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.
