Trypho said: You seem to me to have passed through much controversy with many people about all the subjects under discussion, and therefore are ready to answer everything you are asked. Answer me then first how you can prove that there is another God besides the Maker of the universe, and then you shall prove that He endured even to be born by means of the Virgin.
I said: Allow me first to say some words out of the prophecy of Isaiah, which were spoken about that office of forerunner in which John, who was both Baptist and prophet, was the forerunner of this our Lord Jesus Christ Himself.
He said: By all means do so.
I replied: Isaiah therefore uttered this prediction concerning the forerunning of John. And Hezekiah said unto Isaiah: The word of the Lord is good, which He spake: Let there be peace and righteousness in my days And, Comfort ye the people; speak, ye priests, to the heart of Jerusalem and comfort her, because her humiliation is completed; her sin is loosed, because she received at the hand of the Lord double of her sins. The voice of one crying in the wilderness: Prepare ye the ways of the Lord, make ye the paths of our God straight. Every ravine shall be filled up and every mountain and hill shall be made low, and all the crooked places shall be straight, and the rough places be smooth ways; and the glory of the Lord shall be seen, and all flesh shall see the salvation of God, because the Lord hath spoken.
The voice of one saying: Cry! And I said; What shall I cry? All flesh is grass, and all man’s glory as the flower of grass. The grass withered, and the flower of it fell off — but the word of the Lord remaineth for ever. Go up on a high mountain thou that bringest good news to Sion; Lift up thy voice with strength, thou that bringest good news to Jerusalem. Lift ye it up, be not afraid. Say to the cities of Judah: Behold your God; the Lord, behold. He cometh with strength, and His arm cometh with authority. Behold, the reward is with Him, and the work in front of Him. As a shepherd shall He shepherd His flock, and with His arm shall He gather lambs, and her that is with child shall He encourage.
Who ever measured the water with His hand, and the heaven with a span, and all the earth with one grasp? Who set the mountains by a weight, and the glens by a balance? Who ever knew the mind of the Lord, and who became His counsellor to instruct Him? Or with whom took He counsel, and who instructed Him? Or who showed Him judgment? Or who made known to Him the way of understanding? All the nations are as a drop from a bucket, and as the turn of a scale were they reckoned, and shall be counted as spittle. Even Lebanon was not sufficient to burn, and the four-footed beasts not sufficient for a burnt-offering, and all the nations were nothing, and were counted as nought.Isaiah 40:1-17
