Augustine of Hippo : While the little one is nourished by the example of the one who from greatness descended to humility, the devil has lost what he held: because the proud held only the proud. When such an example of humility was displayed before them, people learned to condemn their own pride and to imitate the humility of God. Thus also the devil, by losing those whom he had in his power, has even himself been humbled; not chastened, but thrown prostrate. "You have humbled the proud like one that is wounded." You have been humbled and have humbled others. You have been wounded and have wounded others, for your blood as it was shed to blot the handwriting of sins could not but wound him. For what was the ground of his pride, except the bond that he held against us? This bond, this handwriting, you have blotted out with your blood. Him therefore you have wounded, from whom you have rescued so many victims. You must understand the devil wounded, not by the piercing of the flesh, which he has not, but by the bruising of his proud heart. "You have scattered your enemies abroad with your mighty arm." — EXPLANATION OF THE Psalms 89:11 Jerome : [Daniel 7:2-3] "And during the night I saw in my vision, and behold, the four winds of heaven strove upon the great sea, and four great beasts were coming up out of the sea, differing from one another." The four winds of heaven I suppose to have been angelic powers to whom the principalities have been committed, in accordance with what we read in Deuteronomy: "When the Most High divided the nations and when He separated the children of Adam, He established the bounds of the peoples according to the number of the angels. For the Lord's portion is His people; Jacob is the line of His inheritance (Deuteronomy 32:8). But the sea signifies this world and the present age, overwhelmed with salty and bitter waves, in accordance with the Lord's own interpretation of the dragnet cast into the sea (Matthew 13:47-50). Hence also the sovereign of all creatures that inhabit the waters is described as a dragon, and his heads, according to David, are smitten in the sea (Psalms 74:13). And in Amos we read: "If he descends to the very depth of the sea, there will I give him over to the dragon and he shall bite him" (Amos 9:3). But as for the four beasts who came up out of the sea and were differentiated from one another, we may identify them from the angel's discourse. "These four great beasts," he says, "are four kingdoms which shall rise up from the earth." And as for the four winds which strove in the great sea, they are called winds of heaven because each one of the angels does for his realm the duty entrusted to him. This too should be noted, that the fierceness and cruelty of the kingdoms concerned are indicated by the term "beasts." — Commentary on Daniel, Chapter Seven
