Quaternion (2)

Hastings' Dictionary of the New Testament

QUATERNION (τετράδιον).—The word occurs only once in NT, and then not in the Gospels (Acts 12:4); but we know that four soldiers at a time were ordinarily told off for work in the Roman army (Vegetius, de Re Milit. iii. 8), and that there were that number in charge of our Lord’s Crucifixion (John 19:23-24; cf. Evang. Petr. 9; see art. Coat).
