Cyril of Alexandria : "I will give a leader to Zion, and I will console Jerusalem as I go." … Again the multitude of those going astray is promised the revealing of the Savior, through whom each one under heaven has been saved and is summoned to the recognition of the truth. So that we could have a guide who would be able and skilled to lead us along the path of salvation, the only-begotten Son of God became a human being. And though he was King by nature in that he is considered to be God and from God the Father and ruler of all things with all creation under his feet, he is said to be elected king among us. — COMMENTARY ON Isaiah 3:5.41:27-28 Eusebius of Caesarea : I want you to know, God is saying, I have intended from the beginning of everything to give authority to my church over all things, and the authority of my kingdom I shall give to my Zion. And I shall stir up my Jerusalem, preparing it as the road on which are all those who labor in it towards the thrice-blessed goal—to the God over all and his heavenly kingdom. — COMMENTARY ON Isaiah 2:21 Jerome : (Verse 27) The first to Zion will say: Behold, they are here, and I will give Jerusalem a messenger. LXX: I will give the beginning to Zion: and I will console Jerusalem in the way. And the Lord will speak first to Zion, that is, to His Church, and He will say to her: See, your children are here, whom I have given to you through my faith. But it signifies the Apostles, who preached the Gospel throughout the whole world. Zion and Jerusalem differ in name; but as one city, so is one Church. — Commentary on Isaiah
