Job 1:12

"[God's] hand" must be understood in a variety of ways. It is either the power that punishes or serves punishment, usually referred to in the Scripture as "tools of wrath," or the protecting and guarding power in the Scripture, "No one can snatch them out …

[Satan] himself willed and desired to receive power over Job, but he did not dare to say so. "But you," he says, "stretch out your hand." Then, so that he may not say, "you indulgently struck him as though he was a household servant," God does not do that which the devil asked. Certainly God could, in doing that, justify himself by saying, "I did what you wanted; it is you who told me to touch him."

ALLEGORICAL INTERPRETATION Whereas we are examining Holy Scripture under its figurative import, by the hand of Satan is to be understood not his power, but the extent of his tempting. All, then, that he hath is given into the hand of the Tempter, and he is only forbidden to put forth his hand upon him, which nevertheless, when his substance is gone, is permitted him; for that first Judaea, which was His possession, was taken from Him in unbelief, and that afterwards His flesh was nailed to the stock of the Cross, He then Who first underwent the opposition of Judaea, and afterwards came even to the Cross, in a manner first lost that He had, and then in His own Person endured the wickedness of the adversary. So Satan went forth from the presence of the Lord. Just as it was said above, Satan went forth from the presence of the Lord, in that he attained the objects of his desire; for he was in a certain sense in His presence, all the time that on account of Him, he failed to accomplish all that he mischievously thirsted after.

Because, as I have said, God wills the virtue of the saints to be known to all, both the just and the wicked, it pleased him that as all saw Job's good deeds that his right intention should also be clearly shown to all. So …

HISTORICAL INTERPRETATION We should mark in the Lord's words the dispensations of heavenly pity, how He lets go our enemy, and keeps him in; how He looses, and yet bridles him. He allows him some things for temptation, but withholds him from others. All that he hath is in thy hand, only upon himself put not forth thine hand. His substance He delivers over, but still He protects his person, which notwithstanding after a while He designs to give over to the tempter; yet He does not loose the enemy to every thing at once, lest he should crush His own subject by striking him on every side. For whenever many evils betide the elect, by the wonderful graciousness of the Creator they are dealt out by seasons, that what by coming all together would destroy, may when divided be borne up against. Hence Paul says, God is faithful, Who will not suffer you to be tempted above that ye are able, but will with the temptation also make a way to escape, that ye may be able to bear it. Hence David says, Examine me, O Lord, and prove me. As if he said in plain words, 'first examine my powers, and then, as I am able to bear, let me undergo temptation.' But this that is said, Behold, all that he hath is in thy power, only upon himself put not forth thine hand, is also capable of another sense, viz. that the Lord knew well, indeed, that His soldier was brave, yet chose to divide for him his contests with the enemy, that, though victory should in every case be sure to that staunch warrior, yet that from one conflict first the enemy might return to the Lord defeated, and that then he might grant him another encounter to be again worsted, so that his faithful follower might come forth the more incomparable conqueror, in proportion as the vanquished foe had repaired his forces again for fresh wars with him.
