rwp@John:12:37 @{Though he had done so many signs before them} (\tosauta autou smeia pepoikotos emprosthen autn\). Genitive absolute with perfect active participle in concessive sense of \poie\. {Yet they believed not on him} (\ouk episteuon eis auton\). No "yet" in the Greek. Negative imperfect active of \pisteu\, "they kept on not believing on him," stubborn refusal in face of the light (verse 35|).
