Acts 16:22-26 New Living Translation (NLT)

²² A mob quickly formed against Paul and Silas, and the city officials ordered them stripped and beaten with wooden rods. ²³ They were severely beaten, and then they were thrown into prison. The jailer was ordered to make sure they didn’t escape. ²⁴ So the jailer put them into the inner dungeon and clamped their feet in the stocks.

²⁵ Around midnight Paul and Silas were praying and singing hymns to God, and the other prisoners were listening. ²⁶ Suddenly, there was a massive earthquake, and the prison was shaken to its foundations. All the doors immediately flew open, and the chains of every prisoner fell off!
