the third hour. Of the day (John 11:9), i.e. 9am. No discrepancy; for the sixth hour of John 19:14 was the sixth hour of the night (from about sunset), viz. "about" midnight (in the midst of the trial), when Pilate said "Behold your King". The context there and here explains and settles the matter. Here, the trial was over; in John 19:14 the trial was going on. See App-156 and App-165. It was the hour of the morning sacrifice.
