11-2 In my previous book, Theophilus, I recorded everything that Jesus did and taught until the day he was taken up to heaven, after giving commandments to his apostles through the Holy Ghost.
Jesus goes to heaven in a cloud
3 After his death, Jesus appeared to his apostles for forty days and showed many infallible proofs.

Matthias replaces Judas
12 Then they returned to Jerusalem from the Mount of Olives.
13 Here's a list of those who were there: Peter, James, John, Andrew, Philip, Thomas, Bartholomew, Matthew, James the son of Alphaeus, Simon Zelotes, and Judas the brother of James.
14 Along with Jesus's brothers, a few women were also there, including his mother, Mary.

16 The Holy Ghost inspired David to say something about Judas who betrayed Jesus.
18 After Judas bought a field with the money he received for betraying Jesus, he fell down and burst apart, causing all of his bowels to gush out.
20 In the Psalms, David says, “Let his house be desolate, and let someone else take his job.”
This is the sequel to the gospel of Luke. It was written by the same unknown author (whose name wasn't Luke).Wikipedia: Luke-Acts
Don't leave Jerusalem. (1:4)
Jesus told his disciples to go to Galilee in Matthew (28:10) and Mark (16:7). In John (21:8-14), he even helps them fish on the Sea of Galilee after his resurrection (Episode 269).
In the previous two verses, the number of believers were listed as the eleven apostles, Jesus's mother and brothers, along with a few unnamed woman. Where did the other 100 or so believers come from?
The Holy Ghost inspired David to say something about Judas (1:16)
A rather obvious exaggeration. The entire population of Jerusalem in the early first century was no more than 30,000. If so, then ten percent of the Jews in Jerusalem converted after hearing Peter call them a bunch of Christ killers? See How many Jews became Christians in the first century?
