In verses Luke 8 and Luke 9 we have one of the dualities or doublets in Matthew ( Luke 5:29-30 ). Jesus repeated his pungent sayings many times. Instead of ei geennan ( Luke 5:29 ) we have ei to pur to aiwnion and at the end of verse Luke 9tou puro is added to thn geennan. This is the first use in Matthew of aiwnio. We have it again in Luke 19:16Luke 19:29 with zoh, in Luke 25:41 with pur, in Luke 25:46 with kolasin and zohn. The word means ageless, without beginning or end as of God ( Romans 16:26 ), without beginning as in Romans 16:25 , without end as here and often. The effort to make it mean "aeonian" fire will make it mean "aeonian" life also. If the punishment is limited, ipso facto the life is shortened. In verse Romans 9 also monopqalmon occurs. It is an Ionic compound in Herodotus that is condemned by the Atticists, but it is revived in the vernacular Koin. Literally one-eyed. Here only and Mark 9:47 in the New Testament.
