{If a man say} (ean tis eip(8869)). Condition of third class
with ean and second aorist active subjunctive. Suppose one say.
Cf.  1:6 . {I love God} (Agap(9320)ton theon). Quoting an imaginary
disputant as in  2:4 . {And hateth} (kai misei). Continuation
of the same condition with ean and the present active
subjunctive, "and keep on hating." See  2:9  3:15  for use of
mise(935c) (hate) with adelphos (brother). A liar (pseust(8873)).
Blunt and to the point as in  1:10  2:4 . {That loveth not} (ho
m(8820)agap(936e)). "The one who does not keep on loving" (present
active negative articular participle). {Hath seen} (he(9372)aken).
Perfect active indicative of hora(935c), the form in  Joh 1:18  used
of seeing God. {Cannot love} (ou dunatai agap(8369)n). "Is not able
to go on loving," with which compare  2:9 , ou dunatai
hamartanein (is not able to go on sinning). The best MSS. do not
have p(9373) (how) here.
