Acts 16:22-25

22The crowd joined the attack against them, and the magistrates tore the clothes off Paul and Silas and ordered them to be beaten with rods.

23After they had beaten them severely, they threw them into prison and commanded the jailer to guard them securely.

24Receiving such orders, he threw them in the inner cell and fastened their feet in the stocks.

25About midnight Paul and Silas were praying and singing hymns to God, and the rest of the prisoners were listening to them.
