Acts 1:4-8

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.”
