Acts 16:22-25

The crowd joined in the attack against them, and the chief magistrates stripped off their clothes and ordered them to be beaten with rods. After they had severely flogged them, they threw them in jail, ordering the jailer to guard them carefully. Receiving such an order, he put them into the inner prison and secured their feet in the stocks. About midnight Paul and Silas were praying and singing hymns to God, and the prisoners were listening to them.
