'Jailer' in the Bible

After striking them many times [with the rods], they threw them into prison, commanding the jailer to guard them securely.

When the jailer, shaken out of sleep, saw the prison doors open, he drew his sword and was about to kill himself, thinking that the prisoners had escaped.

Then the jailer called for torches and rushed in, and trembling with fear he fell down before Paul and Silas,

And the jailer repeated the words to Paul, saying, “The chief magistrates have sent word to release you; so come out now and go in peace.”
