And it was the third hour, and they crucified him. The third hour would literally be nine o'clock. But we gather from Mark 15:33 that our Lord was on his cross, and still alive, at the sixth hour, that is, at twelve o'clock.
The simplest mode of solving the chronological difficulty seems to be this: The Jews divided their day into four parts, which they called hours, namely, the first, from six to nine; the third, from nine to twelve; the sixth, from twelve to three; and the ninth, from three to six.
It was, then, within the third hour, that is, between nine and twelve, that they crucified him; and it was from the sixth to the ninth hour that he was actually upon his cross. St. John employs the Asiatic mode of computing time.
