Acts 1:3-5

1:3 To the same apostles also, after his suffering, he presented himself alive with many convincing proofs. He was seen by them over a forty-day period and spoke about matters concerning the kingdom of God. 1:4 While he was with them, he declared, “Do not leave Jerusalem, but wait there for what my Father promised, which you heard about from me. 1:5 For John baptized with water, but you will be baptized with the Holy Spirit not many days from now.”
