Acts 16:22-25 NIV

[22] The crowd joined in the attack against Paul and Silas, and the magistrates ordered them to be stripped and beaten with rods. [23] After they had been severely flogged, they were thrown into prison, and the jailer was commanded to guard them carefully. [24] When he received these orders, he put them in the inner cell and fastened their feet in the stocks. [25] About midnight Paul and Silas were praying and singing hymns to God, and the other prisoners were listening to them.
