Thracian infantry with rhomphaia.
When Plutarch described the Macedonian army he made note of the fearsome appearance of their Thracian allies:
"First marched the Thracians, who, he himself tells us, inspired him with most terror; they were of great stature, with bright and glittering shields and black frocks under them, their legs armed with greaves, and they brandished, as they moved, straight and heavily-ironed spears over their right shoulders."
rhomphaia is used just two books in the NT: Luke (once, in 2:35), and 6 times in Revelation. Five of those refer to the sword from His mouth. The other is the sword of the ashen horse in Revelation 6:8.
makhaira : this is not used for the sword from His mouth in Revelation
necropolis at nearby Hierapolis, where the water supply of Laodicea originates. Many people were buried at Heirapolis, because they would come to the hot springs for medical treatments, and many of them would retire or die there.
