'Prisoners' in the Bible

But about midnight Paul and Silas were praying and singing hymns unto God, and the prisoners were listening to them;

And the jailor, being roused out of sleep and seeing the prison doors open, drew his sword and was about to kill himself, supposing that the prisoners had escaped.

And when it was determined that we should sail for Italy, they delivered Paul and certain other prisoners to a centurion named Julius, of the Augustan band.

And the soldiers counsel was to kill the prisoners, lest any of them'should swim out, and escape.
