What did Paul shout to stop the Philippian jailer from killing himself?

Answer: We are all here!

Seeing the doors open, the jailer drew his sword, but Paul called out, "Do not harm yourself! We are all here!"

“When the jailer woke up and saw the prison doors open, he drew his sword and was about to kill himself, presuming that the prisoners had escaped. But Paul called out in a loud voice, “Do not harm yourself! We are all here!””— Acts 16:27-28 (BSB)
