Quaternion. A body of four. Acts 12:4-10. Four soldiers were appointed to keep guard during each of the four watches of the night. There were therefore sixteen in all. Of each quaternion probably two were in the prison, Peter being chained to them, and the other two were sentinels before the gate—the first and second guard.
