And he said to me: Thou art my servant Israel, for in thee will I glory. And now saith the Lord, that formed me from the womb to be his servant, that I may bring back Jacob unto him, and Israel will not be gathered together: and I am glorified in the eyes of the Lord, and my God is made my strength. And he said: It is a small thing that thou shouldst be my servant to raise up the tribes of Jacob, and to convert the dregs of Israel. Behold, I have given thee to be the light of the Gentiles, that thou mayst be my salvation even to the farthest part of the earth.

Gospel Reading: John 1:29-34
The next day, John saw Jesus coming to him, and he saith: Behold the Lamb of God, behold him who taketh away the sin of the world. This is he, of whom I said: After me there cometh a man, who is preferred before me: because he was before me. And I knew him not, but that he may be made manifest in Israel, therefore am I come baptizing with water. And John gave testimony, saying: I saw the Spirit coming down, as a dove from heaven, and he remained upon him. And I knew him not; but he who sent me to baptize with water, said to me: He upon whom thou shalt see the Spirit descending, and remaining upon him, he it is that baptizeth with the Holy Ghost. And I saw, and I gave testimony, that this is the Son of God.
