"The Father sets those dates," he replied, "and they are not for you to know.
But when the Holy Spirit has come upon you, you will receive power and will tell people about me everywhere -- in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth."
It was not long after he said this that he was taken up into the sky while they were watching, and he disappeared into a cloud.
As they were straining their eyes to see him, two white-robed men suddenly stood there among them.
They said, "Men of Galilee, why are you standing here staring at the sky? Jesus has been taken away from you into heaven. And someday, just as you saw him go, he will return!"
The apostles were at the Mount of Olives when this happened, so they walked the half mile back to Jerusalem.
Then they went to the upstairs room of the house where they were staying. Here is the list of those who were present: Peter, John, James, Andrew, Philip, Thomas, Bartholomew, Matthew, James (son of Alphaeus), Simon (the Zealot), and Judas (son of James).
They all met together continually for prayer, along with Mary the mother of Jesus, several other women, and the brothers of Jesus.
During this time, on a day when about 120 believers were present, Peter stood up and addressed them as follows:
"Brothers, it was necessary for the Scriptures to be fulfilled concerning Judas, who guided the Temple police to arrest Jesus. This was predicted long ago by the Holy Spirit, speaking through King David.
Judas was one of us, chosen to share in the ministry with us."
