In verses 8 and 9 we have one of the dualities or
doublets in Matthew ( 5:29-30 ). Jesus repeated his pungent
sayings many times. Instead of eis geennan ( 5:29 ) we have
eis to pur to ai(936e)ion and at the end of verse 9 ou puros
is added to (886e) geennan. This is the first use in Matthew of
ai(936e)ios. We have it again in 19:16,29 with zo(885c), in 25:41
with pur, in 25:46 with kolasin and zo(886e). The word means
ageless, without beginning or end as of God ( Ro 16:26 ), without
beginning as in Ro 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 9 also monophthalmon occurs.
It is an Ionic compound in Herodotus that is condemned by the
Atticists, but it is revived in the vernacular _Koin(825f). Literally
one-eyed. Here only and Mr 9:47 in the New Testament.
