Acts 1:4-8

While he was still with them, he said: Don't leave Jerusalem yet. Wait here for the Father to give you the Holy Spirit, just as I told you he has promised to do. John baptized with water, but in a few days you will be baptized with the Holy Spirit. While the apostles were still with Jesus, they asked him, “Lord, are you now going to give Israel its own king again?” Jesus said to them, “You don't need to know the time of those events that only the Father controls. But the Holy Spirit will come upon you and give you power. Then you will tell everyone about me in Jerusalem, in all Judea, in Samaria, and everywhere in the world.”
