Acts 1:12-26

Then the disciples went back to Jerusalem from the Mount of Olives which is about a Sabbath day's walk from Jerusalem. When they arrived, they went upstairs to the upper room where they were staying: Peter, John, James and Andrew; Philip and Thomas; Bartholomew and Matthew; James the son of Alphaeus, Simon the Zealot, and Judas the son of James. They all joined together in prayer, together with the women and Mary, Jesus' mother, and his brothers. At this time Peter stood up and addressed a crowd of around one hundred and twenty believers who had gathered together. “My brothers and sisters,” he said, “The Scriptures, spoken by the Holy Spirit through David, had to be fulfilled regarding Judas, who guided those who arrested Jesus. He was counted as one of us, and shared in this ministry.” (Judas had bought a field with his ill-gotten gains. There he fell down headfirst, and his body burst apart, spilling out all his intestines. Everybody who lived in Jerusalem heard about this so that the field was called in their language “Akeldama,” which means, “Field of blood.”) As it's written in the book of Psalms, “Let his home be abandoned, and no one live there,” and “Let someone else take over his position.” “So now we have to choose someone who has been with us the whole time that Jesus was with us, from the time John was baptizing up until the day Jesus was taken up to heaven from us. One of these must be chosen to join together with us as we witness, giving evidence of Jesus' resurrection.” Two names were put forward: Joseph Justus, also known as Barsabbas, and Matthias. They prayed together and said, “Lord, you know everyone's thoughts. Please show us which of these two you have chosen to replace Judas as an apostle in this ministry that he gave up to go to where he belongs.” They cast lots, and Matthias was chosen. He was counted as an apostle with the other eleven.
