Acts 1:3-8 New International Version (NIV)

³ After his suffering, he presented himself to them and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God. ⁴ On one occasion, while he was eating with them, he gave them this command: “Do not leave Jerusalem, but wait for the gift my Father promised, which you have heard me speak about. ⁵ For John baptized with^[a] water, but in a few days you will be baptized with^[b] the Holy Spirit.”

⁶ Then they gathered around him and asked him, “Lord, are you at this time going to restore the kingdom to Israel?”

⁷ He said to them: “It is not for you to know the times or dates the Father has set by his own authority. ⁸ But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”

Acts 2:14 New International Version (NIV)
