{If ye were blind} (ei tuphloi (8874)e). Condition of second
class with imperfect indicative in the protasis. The old word
	uphlos is from 	uph(935c), to raise a smoke, to blind by smoke
(literally and metaphorically). Here, of course, it is moral
blindness. If the Pharisees were born morally blind, they would,
like idiots, be without responsibility. {Ye would not have sin}
(ouk an eichete hamartian). Regular form for conclusion of
second-class condition, an with imperfect. {But now ye say}
(
un de legete). In contrast to the previous condition. See
like contrast in  15:22,24 . They arrogantly asserted superior
knowledge. {We see} (lepomen). The ignorant mob do not
( 7:49 ). It is sin against light and is hopeless ( Mr 3:29  Mt
12:31f. ). "Ye are witnesses against yourselves" (martureite
heautois,  Mt 23:31 ).
