Robertson's Word Pictures (NT)
If ye were blind (ei tufloi hte). Condition of second class with imperfect indicative in the protasis. The old word tuflov is from tufw, 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 eixete amartian). Regular form for conclusion of second-class condition, an with imperfect.
But now ye say (nun de legete). In contrast to the previous condition. See like contrast in John 15:22, John 15:24. They arrogantly asserted superior knowledge.
We see (blepomen). The ignorant mob do not (John 7:49). It is sin against light and is hopeless (Mark 3:29; Matthew 12:31 f.). "Ye are witnesses against yourselves" (martureite eautoiv, Matthew 23:31).
