"For where jealousy and faction are, there is confusion and every vile deed." — James 3:16 (ASV)

Confusion (ακαταστασια). Late word (from ακαταστατος), 1:8; 3:8), a state of disorder (1 Corinthians 14:33).

Vile (φαυλον). Kin to German faul, first slight, ordinary, then bad. The steps are cheap, paltry, evil. Opposed to αγαθα (good) in Joh 5:39.
