Acts 9:23

And when many days were fulfilled, the Jews took counsel together to kill him.

When many days were fulfilled ... It is obvious that Luke did not here stress the exact chronology of the events narrated. Boles gave, as the probable chronology of the events in view here, the following:

Saul was struck down on the Damascus road (Acts 9:3-8).

Three days of blindness and prayer (Acts 9:8).

Sight restored, baptized and received the Holy Spirit (Acts 9:10-19).

Preached Christ and confounded the Jews (Acts 9:19-22).

Made a sudden departure to Arabia for further study and communion with God (Galatians 1:17,18).

Came back to Damascus and renewed his preaching with such force that the Jews decided to kill him (Acts 9:23). (This was three years after his baptism.)

The plot to kill Paul was discovered, and he escaped to Jerusalem (Acts 9:24,25).

The Christians were afraid of him (Acts 9:26).

Barnabas took up his cause and recommended him (Acts 9:27-29).

Paul began preaching where Stephen left off (Acts 9:29).

There was another plot to kill him (Acts 9:29).

The Jerusalem church sent him to Tarsus (Acts 9:30).[22]
