Christ must be understood to be an exterminator of spiritual foes, who wields spiritual arms and fights in spiritual strife.… It is of such a war as this that the psalm may evidently have spoken: “The Lord is strong, the Lord is mighty in battle.” For with the last enemy death did he fight, and through the trophy of the cross he triumphed.
Lord of Sabaoth is translated “Lord of powers.” And he is the captain of the powers of the Lord, whom also the divine powers salute as Lord of Sabaoth in Psalm 24, foretelling his return from earth to heaven.… In the Hebrew he is here again called Lord of Sabaoth. And since he is the King of glory, and by his sojourn here the whole earth would be filled with his glory, both in the psalm and in the prophecy the fulfillment is rightly placed in the present: in the prophecy in the words, “The whole earth is full of his glory,” in the psalm at the beginning where it says, “The earth is the Lord’s and the fullness thereof, the world and all that dwell therein.”
[Daniel 8:16-17] "And I heard the voice of a man in the midst of the Ulai, and he cried out and said: 'Gabriel, make this vision intelligible (Vulgate: make this man to understand the vision).' And he came and stood near to where I was standing." The Jews claim that this man who directed Gabriel to explain the vision to Daniel was Michael. Quite appropriately it was Gabriel, who has been put in charge of battles, to whom this duty was assigned, inasmuch as the vision had to do with battles and contests between kings and even between kingdoms themselves. For Gabriel is translated into our language as "the strength of, or the mighty one of, God." And so at that time also when the Lord was about to be born and to declare war against the demons and to triumph over the world, Gabriel came to Zacharias (Luke 1:11-20) and to Mary (Luke 1:26-27). And then we read in the Psalms concerning the Lord in His triumph: "Who is this king of glory? The Lord strong and mighty, the Lord mighty in battle; He is the King of glory" (Psalm 24:8). But whenever it is medicine or healing that is needed, it is Raphael who is sent, for his name is rendered as "the healing of," or "the medicine of God" - that is, if one cares to accept the authority of the Book of Tobias (Tobit 12:11-15). And then, when favorable promises are made to the people, and hilasmos, which we might render as "propitiation" or "expiation," is the thing required, then it is Michael who is directed to go, for his name means, "Who is like God?" Of course the significance of the name indicates the fact that the only true remedy is to be found in God.
"And he said to me: 'Son of man, understand that in the time of the end the vision shall be fulfilled.'" Inasmuch as Ezekiel and Daniel and Zechariah behold themselves to be often in the company of angels, they were reminded of their frailty, lest they should be lifted up in pride and imagine themselves to partake of the nature or dignity of angels. Therefore they are addressed as sons of men, in order that they might realize that they are but human beings.
"Who is this King of glory?" Mortal nature is awe-struck in wonder, and asks, "Who is this King of glory?" "The Lord strong and mighty." He whom you deemed weak and overwhelmed. "The Lord mighty in battle" [Psalm 24:8]. Handle the scars, and you will find them made whole, and human weakness restored to immortality. The glorifying of the Lord, which was owing to earth, where It warred with death, has been paid.
[AD 220] Tertullian on Psalms 24:8
