{He was in the world} (en t(9369) kosm(9369) (886e)). Imperfect tense
of continuous existence in the universe before the Incarnation as
in verses  1,2 . {Was made by him} (di' autou egeneto).
"Through him." Same statement here of "the world" (ho kosmos)
as that made in verse  3  of panta. {Knew him not} (auton ouk
egn(935c)). Second aorist active indicative of common verb ginosk(935c),
what Gildersleeve called a negative aorist, refused or failed to
recognize him, his world that he had created and that was held
together by him ( Col 1:16 ). Not only did the world fail to know
the Pre-incarnate Logos, but it failed to recognize him when he
became Incarnate ( Joh 1:26 ). Two examples in this sentence of
John's fondness for kai as in verses  1,4,5,14 , the paratactic
rather than the hypotactic construction, like the common Hebrew
use of _wav_.
