Paul and Silas

Who weren't "seized" along with "Paul and Silas" (Acts 16:19)?
Timothy and Luke

Why not?
They somehow may not have been recognized as companions of Paul and Silas, or they may not have been around when Paul and Silas were seized.

What other possible reasons are there for Luke and Timothy not having been seized along with Paul and Silas?
Paul and Silas were "Jews" (Acts 16:20), which Luke wasn't, and Timothy may have been too young to be considered among "men" (Acts 16:20) and/or let off because he was only half Jewish, as "his father was Greek" (Acts 16:1).

What three errors are found in the accusations against Paul and Silas?
Paul and Silas didn't "trouble" (Acts 16:20) anyone. They didn't "teach customs which are not lawful" (Acts 16:21). And they were both Roman citizens (see Acts 16:37 in Magistrates).

What was the real reason for Paul and Silas getting "dragged into the marketplace" (Acts 16:19)?
The owners of the slave girl who had been possessed with a spirit of divination were angry that "their hope of profit was gone" (Acts 16:19).

Who are "the magistrates" (Acts 16:22)?
See Magistrates.

What should the magistrates have done?
They should have sought evidences for the accusations against Paul and Silas, and then given them the opportunity to present their defense. Instead of conducting a trial and rendering a verdict, they went along with the racist mob and skipped directly to pronouncing and executing the punishment.

What was the punishment?
Getting "beaten with rods" (Acts 16:22) and then imprisoned.

Was this fair to Paul and Silas?
Not really

How did they react to being falsely accused, unjustly beaten and jailed?
By "praying and singing hymns to God" (Acts 16:25)

Why?
Great was their reward in heaven, as Jesus promised: "Blessed are those who are persecuted for righteousness’ sake, for theirs is the kingdom of heaven. Blessed are you when they revile and persecute you, and say all kinds of evil against you falsely for My sake. Rejoice and be exceedingly glad, for great is your reward in heaven, for so they persecuted the prophets who were before you" (Matthew 5:10-12). And "the prisoners were listening to them" (Acts 16:25).

Why would the other prisoners listen to Paul and Silas instead of telling to shut up for making noise at midnight?
επηκροωντο (epekroonto), the original Greek verb translated "listening," means to "listen attentively." Not only was the content of what Paul and Silas were praying and singing worthy of attention, but it was coming from two men who had just been beaten and should have been angry at the world.

How do you react when you are teased, mocked, insulted or persecuted for Christ?
 

Why would "the keeper of the prison" try to "kill himself" (Acts 16:27)?
A Roman guard's failure to guard a prisoner was a capital crime. "Seeing the prison doors open, supposing the prisoners had fled" (Acts 16:27), he thought he was as good as dead.

Why did he run and fall "down trembling before Paul and Silas" (Acts 16:29)?
He had just witnessed at least three miracles.

Which three?
For one, "all the doors were opened" (Acts 16:26). For another, none of the prisoners had left; his life had been spared. Third, Paul had seen him through the darkness trying to kill himself, before he - the jailer - "called for a light" (Acts 16:29).

What would you expect him to have done at this point?
Thank Paul, Silas and the other prisoners for having stayed, put the chains back on them and lock their doors before they change their minds about not escaping, and consider himself fortunate for his own life in effect having been spared.
