Acts 1 is the first chapter of the Acts of the Apostles in the New Testament of the Christian Bible. The book containing this chapter is anonymous but early Christian tradition affirmed that Luke composed this book as well as the Gospel of Luke. This chapter functions as a transition from the "former account" (that is, Gospel of Luke) with a narrative prelude (verses 1–5), repeated record of the ascension of Jesus Christ with more detail (verses 6–11) and the meeting of Jesus' followers (verses 12-26), until before Pentecost. Text The original text was written in Koine Greek and is divided into 26 verses.

Ascension of Jesus (1:6–12) This section records that forty days after the resurrection, Jesus commands the disciples during a meal to await the coming of the Holy Spirit, then a cloud takes him upward from sight, and two men in white appear to tell them (the disciples) that he will
