And I will wait, &c.— These words belong to the Messiah. The Messiah here answers God the Father, that he perfectly acquiesces in his counsel, waiting with confidence reposed in him for the completion of those great promises which were made to him by the Father, as well as those in ch. 49 though God hid his face from the greater part of the rebellious and unbelieving Jews. The children, mentioned Isaiah 8:18 are generally thought to refer to the apostles, and first disciples of Christ, who were indeed for signs and for wonders in Israel. See Vitringa.
