Acts 1:1-5
1 Theophilus, the first scroll I wrote concerned everything Jesus did and taught from the beginning, 2 right up to the day when he was taken up into heaven. Before he was taken up, working in the power of the Holy Spirit, Jesus instructed the apostles he had chosen. 3 After his suffering, he showed them that he was alive with many convincing proofs. He appeared to them over a period of forty days, speaking to them about God’s kingdom.4 While they were eating together, he ordered them not to leave Jerusalem but to wait for what the Father had promised. He said, “This is what you heard from me: 5 John baptized with water, but in only a few days you will be baptized with the Holy Spirit.”
