¹²Then [the apostles] returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a Sabbath day’s journey away. ¹³And when they had entered, they went up to the upper room, where they were staying, Peter and John and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaeus and Simon the Zealot and Judas the son of James. ¹⁴All these with one accord were devoting themselves to prayer, together with the women and Mary the mother of Jesus, and his brothers.

¹⁵In those days Peter stood up among the brothers (the company of persons was in all about 120) and said, ¹⁶“Brothers, the Scripture had to be fulfilled, which the Holy Spirit spoke beforehand by the mouth of David concerning Judas, who became a guide to those who arrested Jesus. ¹⁷For he was numbered among us and was allotted his share in this ministry.” ¹⁸(Now this man bought a field with the reward of his wickedness, and falling headlong he burst open in the middle and all his bowels gushed out. ¹⁹And it became known to all the inhabitants of Jerusalem, so that the field was called in their own language Akeldama, that is, Field of Blood.) ²⁰“For it is written in the Book of Psalms,

“‘May his camp become desolate,

and let there be no one to dwell in it’;

and

“‘Let another take his office.’

²¹So one of the men who have accompanied us during all the time that the Lord Jesus went in and out among us, ²²beginning from the baptism of John until the day when he was taken up from us—one of these men must become with us a witness to his resurrection.” ²³And they put forward two, Joseph called Barsabbas, who was also called Justus, and Matthias. ²⁴And they prayed and said, “You, Lord, who know the hearts of all, show which one of these two you have chosen ²⁵to take the place in this ministry and apostleship from which Judas turned aside to go to his own place.” ²⁶And they cast lots for them, and the lot fell on Matthias, and he was numbered with the eleven apostles.

⁹If we receive the testimony of men, the testimony of God is greater, for this is the testimony of God that he has borne concerning his Son. ¹⁰Whoever believes in the Son of God has the testimony in himself. Whoever does not believe God has made him a liar, because he has not believed in the testimony that God has borne concerning his Son. ¹¹And this is the testimony, that God gave us eternal life, and this life is in his Son. ¹²Whoever has the Son has life; whoever does not have the Son of God does not have life.

¹³I write these things to you who believe in the name of the Son of God that you may know that you have eternal life. ¹⁴And this is the confidence that we have toward him, that if we ask anything according to his will he hears us. ¹⁵And if we know that he hears us in whatever we ask, we know that we have the requests that we have asked of him.

[Jesus said:] “Holy Father, keep them in your name, which you have given me, that they may be one, even as we are one. ¹²While I was with them, I kept them in your name, which you have given me. I have guarded them, and not one of them has been lost except the son of destruction, that the Scripture might be fulfilled. ¹³But now I am coming to you, and these things I speak in the world, that they may have my joy fulfilled in themselves. ¹⁴I have given them your word, and the world has hated them because they are not of the world, just as I am not of the world. ¹⁵I do not ask that you take them out of the world, but that you keep them from the evil one. ¹⁶They are not of the world, just as I am not of the world. ¹⁷Sanctify them in the truth; your word is truth. ¹⁸As you sent me into the world, so I have sent them into the world. ¹⁹And for their sake I consecrate myself, that they also may be sanctified in truth.”
