rwp@John:9:30 @{Why, herein is the marvel} (\en touti gar to thaumaston estin\). This use of \gar\ (\ge + ara\, accordingly indeed) to bring out an affirmation from the previous words is common enough. "Why in this very point is the wonder" (\thaumaston\, old verbal adjective from \thaumaz\ as in kjv@Matthew:21:42|). The man is angry now and quick in his insight and reply. You confess your ignorance of whence he is, ye who know everything, "and yet (adversative use of \kai\ again) he opened my eyes" (\kai noixen mou tous ophthalmous\). That stubborn fact stands.
