Thou art not yet fifty years old (penthkonta eti oupw ecei). Literally, "Thou hast not yet fifty years." Not meaning that Jesus was near that age at all. It was the crisis of completed manhood ( Numbers 4:3 ) and a round number. Jesus was about thirty to thirty-three. And hast thou seen Abraham? (Kai Abraam ewraka;). So A C D and B W Theta have ewrake, both second person singular of the perfect active indicative of oraw. But Aleph, Sin-syr., Coptic versions (accepted by Bernard) have kai Abraam ewrake se? "Has Abraam seen thee?" Either makes sense here.
