Acts 16:19-24

They are publicly teaching customs which are unlawful for us, as Romans, to accept or observe.” The crowd also joined in the attack against them, and the chief magistrates tore their robes off them and ordered that Paul and Silas be beaten with rods. [2 Cor 11:25] After striking them many times [with the rods], they threw them into prison, commanding the jailer to guard them securely. He, having received such a [strict] command, threw them into the inner prison (dungeon) and fastened their feet in the stocks [in an agonizing position].
