Isaiah 29:24Meaning & Commentary from the Church Fathers

However, they pursued Him not only for allegedly violating the Sabbath but also for claiming that He and His Father are one, making God equal to God (John 5:18). Thus, those who grumble will eventually learn to listen; the uninformed will gain the ability to speak peace. For those who once uttered unjust words about Christ were ignorant; yet they will be taught, he says, to declare righteousness about Him, proclaiming peace while turning away from their former folly, humbling their hearts before Him. Jesus states that peace is found by anyone who calls, ‘Our Lord God, deliver us! For apart from You, we know no other; we invoke Your name.’

His countenance will show embarrassment, and this shame will serve as a path to salvation, particularly when they see that their children—namely, the apostles and those who came after them, descended from the Jews—are performing righteous deeds among the nations and proclaiming the name of Christ, uttering, Our Father who art in heaven, hallowed be thy name. For they will honor the Holy One who emerged from Jacob and instruct others about the God of Israel among the nations, so that they may abandon idols and recognize, "What empty idols our forefathers followed, and none among them brings forth rain." Those who now stray in spirit will come to know God, and those who once grumbled in the wilderness against the Lord will acquire the law they previously lacked. Had they accepted Moses, they would have also accepted the Lord Jesus Christ, for Moses spoke of Him. The message captured at the beginning of the chapter in relation to the Hebrew text: Thus says the Lord to the house of Jacob, who once saved Abraham and took him from Chaldea to the promised land, is indeed clear. However, the phrase translated as concerning the house of Jacob, who was separated from Abraham, can be understood as a reference to the separation of the scribes and Pharisees, who blasphemed the Lord, from Abraham, who rejoiced at the sight of the Lord’s day. For if they truly were Abraham's children, they would perform the works of Abraham. The apostle asserts that those who possess faith akin to Abraham's are deemed his children, including the Gentile nations, who, not through works but through faith, are called children of Abraham.
