Ephrem the Syrian : "Behold, my servant shall be wise," that is, shall be illustrious; these words certainly concern our Lord. Indeed, he was called a servant by his Father, because, in the first place, he was sent by his Father in order to fulfill his will in procuring salvation for all humankind, and in the second place, because he assumed the aspect of a servant. "He shall be exalted and lifted up, and he shall be very high" through his virtues and miracles. — COMMENTARY ON Isaiah 52:13 Jerome : (Verse 13.) Behold, my servant shall understand, he shall be exalted and extolled, and shall be very high. LXX: Behold, my servant shall understand, and he shall be exalted, and shall be very glorious. So that there may be no ambiguity for readers, it is clear who will say: I, who spoke, am here; and the holy arm of the Lord, which has been revealed to all nations, God the Almighty Father clearly teaches: Behold my servant or my son whom I have sent, about whom we have spoken of his difference before. But he emptied himself, taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross (Philippians 2). Therefore God has highly exalted him and bestowed on him the name that is above every name. As it is written in the psalm: I will bless the Lord who gives me understanding (Psalms 16:7); and concerning him, David sings: Who made the heavens with understanding (Psalms 135:5). He Himself is indeed wisdom and understanding, who progressed in wisdom and understanding as if a child in age and wisdom: of whom Peter also speaks: God of our fathers has glorified His Son Jesus, whom you indeed handed over and denied in the presence of Pilate who was willing to release Him. But you denied the Holy and Righteous One (Acts 3:13-14), of whom we have also shown above: I am a witness, says the Lord, and the chosen child upon whom many will marvel when they perceive His signs (Isaiah 43:10). — Commentary on Isaiah
