Acts 1:4-14

Once when he was eating with them, he told them not to leave Jerusalem. He said, “Wait here to receive the promise from the Father which I told you about. John baptized people with water, but in a few days you will be baptized with the Holy Spirit.” When the apostles were all together, they asked Jesus, “Lord, are you now going to give the kingdom back to Israel?” Jesus said to them, “The Father is the only One who has the authority to decide dates and times. These things are not for you to know. But when the Holy Spirit comes to you, you will receive power. You will be my witnesses—in Jerusalem, in all of Judea, in Samaria, and in every part of the world.” After he said this, as they were watching, he was lifted up, and a cloud hid him from their sight. As he was going, they were looking into the sky. Suddenly, two men wearing white clothes stood beside them. They said, “Men of Galilee, why are you standing here looking into the sky? Jesus, whom you saw taken up from you into heaven, will come back in the same way you saw him go.” Then they went back to Jerusalem from the Mount of Olives. (This mountain is about half a mile from Jerusalem.) When they entered the city, they went to the upstairs room where they were staying. Peter, John, James, Andrew, Philip, Thomas, Bartholomew, Matthew, James son of Alphaeus, Simon (known as the Zealot), and Judas son of James were there. They all continued praying together with some women, including Mary the mother of Jesus, and Jesus’ brothers.
