Acts 16:28

But about midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them.

Suddenly there was a great earthquake, so that the foundations of the prison were shaken; and immediately all the doors were opened, and everyone’s bonds were loosened.

The jailer, being roused out of sleep and seeing the prison doors open, drew his sword and was about to kill himself, supposing that the prisoners had escaped.

He called for lights, sprang in, fell down trembling before Paul and Silas,

brought them out, and said, “Sirs, what must I do to be saved?”

They said, “Believe in the Lord Jesus Christ, and you will be saved, you and your household.”
