Dr. Doug Penney, Associate Professor of Classical Languages at Wheaton College, calls attention to Mark 5:9 (Luke 8:30) in which a group of demons declare their name to be Λεγιών, translated as Legion. The naming of various demons and angels in ancient Jewish traditions is a fascinating topic in its own right. Intertestamental angelology often derived such names from creative readings of Hebrew scripture passages. Dr. Penney traces out the linguistic path from Ps. 91:7, through these complex traditions, to Mark 5.
