Acts 16:25-28

About midnight Paul and Silas were praying and singing songs to God as the other prisoners listened. Suddenly, there was a strong earthquake that shook the foundation of the jail. Then all the doors of the jail broke open, and all the prisoners were freed from their chains. The jailer woke up and saw that the jail doors were open. Thinking that the prisoners had already escaped, he got his sword and was about to kill himself. But Paul shouted, “Don’t hurt yourself! We are all here.”
