Luke assumes that his readers will know that death was the punishment in the Roman Empire for allowing prisoners to escape. The jailer thought his prisoners had escaped, and he preferred to commit suicide rather than face trial and execution. You can include this information if your readers need it to understand this sentence. Alternate translation: [he was about to kill himself, because he thought that his prisoners had escaped and he knew that he would be tried and executed for allowing them to escape]

If your language does not use this passive form, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [that the prison doors were open]
