Acts 16:25-34 New International Version (NIV)

²⁵ About midnight Paul and Silas were praying and singing hymns to God, and the other prisoners were listening to them. ²⁶ Suddenly there was such a violent earthquake that the foundations of the prison were shaken. At once all the prison doors flew open, and everyone’s chains came loose. ²⁷ The jailer woke up, and when he saw the prison doors open, he drew his sword and was about to kill himself because he thought the prisoners had escaped. ²⁸ But Paul shouted, “Don’t harm yourself! We are all here!”

²⁹ The jailer called for lights, rushed in and fell trembling before Paul and Silas. ³⁰ He then brought them out and asked, “Sirs, what must I do to be saved?”

³¹ They replied, “Believe in the Lord Jesus, and you will be saved—you and your household.” ³² Then they spoke the word of the Lord to him and to all the others in his house. ³³ At that hour of the night the jailer took them and washed their wounds; then immediately he and all his household were baptized. ³⁴ The jailer brought them into his house and set a meal before them; he was filled with joy because he had come to believe in God—he and his whole household.
