1In my former book, Theophilus, I wrote about all that Jesus began to do and to teach 2until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen. 3After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God. 4On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. 5For John baptized with#1:5 Or in water, but in a few days you will be baptized with#1:5 Or in the Holy Spirit.” 6Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?” 7He said to them: “It is not for you to know the times or dates the Father has set by his own authority. 8But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” 9After he said this, he was taken up before their very eyes, and a cloud hid him from their sight. 10They were looking intently up into the sky as he was going, when suddenly two men dressed in white stood beside them. 11“Men of Galilee,” they said, “why do you stand here looking into the sky? This same Jesus, who has been taken from you into heaven, will come back in the same way you have seen him go into heaven.” 12Then the apostles returned to Jerusalem from the hill called the Mount of Olives, a Sabbath day’s walk#1:12 That is, about 5/8 mile or about 1 kilometer from the city. 13When they arrived, they went upstairs to the room where they were staying. Those present were Peter, John, James and Andrew; Philip and Thomas, Bartholomew and Matthew; James son of Alphaeus and Simon the Zealot, and Judas son of James. 14They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers. 15In those days Peter stood up among the believers (a group numbering about a hundred and twenty) 16and said, “Brothers and sisters,#1:16 The Greek word for brothers and sisters (adelphoi) refers here to believers, both men and women, as part of God’s family; also in 6:3; 11:29; 12:17; 16:40; 18:18, 27; 21:7, 17; 28:14, 15. the Scripture had to be fulfilled in which the Holy Spirit spoke long ago through David concerning Judas, who served as guide for those who arrested Jesus. 17He was one of our number and shared in our ministry.” 18(With the payment he received for his wickedness, Judas bought a field; there he fell headlong, his body burst open and all his intestines spilled out. 19Everyone in Jerusalem heard about this, so they called that field in their language Akeldama, that is, Field of Blood.) 20“For,” said Peter, “it is written in the Book of Psalms: “ ‘May his place be deserted; let there be no one to dwell in it,’#1:20 Psalm 69:25 and, “ ‘May another take his place of leadership.’#1:20 Psalm 109:8 21Therefore it is necessary to choose one of the men who have been with us the whole time the Lord Jesus was living among us, 22beginning from John’s baptism to the time when Jesus was taken up from us. For one of these must become a witness with us of his resurrection.” 23So they nominated two men: Joseph called Barsabbas (also known as Justus) and Matthias. 24Then they prayed, “Lord, you know everyone’s heart. Show us which of these two you have chosen 25to take over this apostolic ministry, which Judas left to go where he belongs.” 26Then they cast lots, and the lot fell to Matthias; so he was added to the eleven apostles.
