'Jailer' in the Bible

When they had struck them with many blows, they threw them into prison, commanding the jailer to guard them securely;

When the jailer awoke and saw the prison doors opened, he drew his sword and was about to kill himself, supposing that the prisoners had escaped.

And the jailer reported these words to Paul, saying, “The chief magistrates have sent to release you. Therefore come out now and go in peace.”
