Cyril of Alexandria : This forecasts the coming of the Savior and our redemption by his coming. It also foretells the granting of riches to those who believe in him.… Concerning that which is new, that is, the church, it may be fittingly said that it is the daughter of Zion.… For whom does he order to proclaim good news to Zion? Those holy spiritual guides, of course, who took on the leadership role in the church and whose job it was to open the gates and to remove the stones from their midst. And what were they to announce? "That the Savior has come bringing his own reward and his work before his face." Two points are made, that which relates to his godhead and that which is a reward for us. Through both the Savior's glory becomes apparent. — COMMENTARY ON Isaiah 5:5.62:11-12 Theodoret of Cyrus : Thus, what God has indicated to the ends of the earth is not the reconstruction of Jerusalem but the cross, the passion, the resurrection, the ascension of the Master to the heavens, the coming of the Holy Spirit and the hope of future benefits. He commands the heralds to prepare the road and to make it level … by removing difficulties. For he calls obstacles "stones." … Then, once the route has been arranged, he ordains the heralds to say to the daughter of Zion, that is, to the church extended throughout the world, "Behold, your Savior has come to you, having his reward and his work before his face." — COMMENTARY ON Isaiah 19:62.10-11
