πῦρ [14 verses](noun sg neut acc) "Fire" is pyr (pur), which means "fire," "sacrificial fire," "funeral fire," "hearth-fire," "lightning," "the light of torches," and "heat of fever." -- "Fire" is a noun that means "fire," "sacrificial fire," "funeral fire," and so on, but Christ only uses this word to describe the fire of a trash dump. He usually uses it with the word that is translated as "hell" but which was the name of the burning trash dump outside of Jerusalem. Though the word appears in sixteen verses of the KJV, two of those verses do not appear in today's Greek source and modern versions of the Bible.
