Conceive, for example, how great a thing it was to see a man after thirty years coming down from the wilderness, being the son of a chief priest, who had never known the common wants of men, and was on every account venerable, and had Isaiah with him. For he too was present proclaiming him, and saying, “This is he who I said should come crying, and preaching throughout the whole wilderness with a clear voice.” For so great was the earnestness of the prophets touching these things, that not their own Lord only, but him also who was to minister unto Him, they proclaimed a long time beforehand, and they not only mentioned him, but the place too in which he was to abide, and the manner of the doctrine which he had to teach when he came, and the good effect that was produced by him.
