Job 1:7

And the Lord said to the devil, Where are you from? The answer to this question is the reconciliation of and what he has done and the permission given to him to act afterwards. The question itself is the divine power, which does not allow us to do what we want, because "the impious will be questioned on his thoughts (Wis. 1:9),” to make known to us.

MORAL INTERPRETATION Satan's going to and fro in the earth is his exploring the hearts of the carnal, and seeking diligently whence he may find grounds of accusation against them. He 'goeth round about the earth,' for he comes about the hearts of men, that he may carry off all that is good in them, that he may lodge evil in their minds, that he may heap up on that he has lodged, that he may perfect that he has heaped, that he may gain as his fellows in punishment those whom he has perfected in sin. And observe that he does not say that he has been flying through the earth, but that he has been walking up and down in it; for, in truth, he is never quick to leave whomsoever he tempts; but there where he finds a soft heart, he plants the foot of his wretched persuasion, so that by resting thereon, he may stamp the prints of evil practice, and by a like wickedness to his own may render reprobate all whom he is able.

ALLEGORICAL INTERPRETATION In the day Satan is demanded of his ways, for that in the light of revealed Wisdom the snares of the hidden foe are discovered. Because, then, the devil is rebuked by the Incarnate Lord, and restrained from his baneful license, it is well subjoined, And the Lord said unto Satan, Whence comest thou? For He then by arraigning attainted the ways of Satan, when by the Advent of the Mediator restraining the wickedness of his persuasions, He rebuked the same. And it is not without reason that the sons of God are related to have stood in the presence of the Lord on this day, forasmuch as it is by the light of Wisdom illuminating them that all the elect are gathered to the calling of their eternal country. Who, though Incarnate Wisdom came to assemble them in actual deed, were yet by virtue of His foreknowledge already inwardly present to His Divinity. But since the old enemy, at the coming of the Redeemer, is questioned of his ways, let us hear what he says. For from the time of Adam till the coming of the Lord, he drew after him all the nations of the Gentiles; he went to and fro in the earth, and walked up and down in it, in that he stamped the foot-prints of his wickedness throughout the hearts of the Gentiles. For when he fell from on high he gained lawful possession of the minds of men, because he fastened them as willing captives in the chains of his iniquity; and he wandered the more at large in the world, in proportion as there was no one found who was in all things free from that his guilt. And his having gone to and fro in the world as with power, is his having found no man who could thoroughly resist him. But now let Satan return back, i.e. let the Divine power withhold him from the execution of his wickedness, since He has now appeared in the flesh, Who had no part in the infection of sin from the infirmity of the flesh. He came in humility for the proud enemy himself to wonder at, that he who had set at nought all the mightiness of His Divinity, might stand in awe even of the very infirmities of His Humanity.
