Thou art not yet fifty years old (pentēkonta eti oupō echeis). Literally, “Thou hast not yet fifty years.” Not meaning that Jesus was near that age at all. It was the crisis of completed manhood (Num 4:3) and a round number. Jesus was about thirty to thirty-three.
And hast thou seen Abraham? (Kai Abraam heōrakas). So A C D and B W Theta have heōrakes, both second person singular of the perfect active indicative of horaō. But Aleph, Sin-syr., Coptic versions (accepted by Bernard) have kai Abraam heōrake sė “Has Abraam seen thee?” Either makes sense here.
