Acts 12:4-6

Darby(i) 4 whom having seized he put in prison, having delivered him to four quaternions of soldiers to keep, purposing after the passover to bring him out to the people. 5 Peter therefore was kept in the prison; but unceasing prayer was made by the assembly to God concerning him. 6 And when Herod was going to bring him forth, that night Peter was sleeping between two soldiers, bound with two chains, and guards before the door kept the prison.
