Acts 1:8-14Revised Standard Version (RSV)
8 But you shall receive power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Samar′ia and to the end of the earth.” 9 And when he had said this, as they were looking on, he was lifted up, and a cloud took him out of their sight. 10 And while they were gazing into heaven as he went, behold, two men stood by them in white robes, 11 and said, “Men of Galilee, why do you stand looking into heaven? This Jesus, who was taken up from you into heaven, will come in the same way as you saw him go into heaven.”
Matthias Chosen to Replace Judas
12 Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a sabbath day’s journey away; 13 and 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. 14 All these with one accord devoted themselves to prayer, together with the women and Mary the mother of Jesus, and with his brothers.
