Acts 1:15-17, 21-26
1:15 In those days Peter stood up among the believers (together the crowd numbered about one hundred twenty persons) and said,
1:16 "Friends, the scripture had to be fulfilled, which the Holy Spirit through David foretold concerning Judas, who became a guide for those who arrested Jesus --
1:17 for he was numbered among us and was allotted his share in this ministry."
1:21 So one of the men who have accompanied us during all the time that the Lord Jesus went in and out among us,
1:22 beginning from the baptism of John until the day when he was taken up from us--one of these must become a witness with us to his resurrection."
1:23 So they proposed two, Joseph called Barsabbas, who was also known as Justus, and Matthias.
1:24 Then they prayed and said, "Lord, you know everyone's heart. Show us which one of these two you have chosen
1:25 to take the place in this ministry and apostleship from which Judas turned aside to go to his own place."
1:26 And they cast lots for them, and the lot fell on Matthias; and he was added to the eleven apostles.
