'Jailer' in the Bible

When they had laid many stripes on them, they threw them into prison, charging the jailer to keep them safely,

The jailer, 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.

The jailer reported these words to Paul, saying, "The magistrates have sent to let you go; now therefore come out, and go in peace."
