Acts 1:13-2:4

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, 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,’ Psalm 69:25 and, “ ‘May another take his place of leadership.’ 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.

The Holy Spirit Comes at Pentecost 1When the day of Pentecost came, they were all together in one place. 2Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. 3They saw what seemed to be tongues of fire that separated and came to rest on each of them.

4All of them were filled with the Holy Spirit and began to speak in other tongues Or languages; also in verse 11 as the Spirit enabled them.
