echthros

ἐχθροὶ[12 verses] (adj pl masc nom ) "Enemy" is echthros, which means "the hated," "the hateful," "the hostile," "the enemy," "the alienated," and "the hating." -- -- The word translated as "foes" primarily means "hated," "hater,"  "hateful," and "hating." It is an adjective used as a noun. The use of this word is very specific in Greek literature. It describes one who was a friend, but who has been alienated and refuses to be reconciled. It is from a rare Greek word meaning "hate," but it is not from the Greek word that Jesus uses for hate. It is usually translated as "enemy" in the KJV.  However, from Jesus's point of view "the enemy" seems to be "hating" others.
