8 Now take also another testimony in the 87th Psalm, where Christ speaks in the Prophets, (for He who then spoke came afterwards among us): O Lord, God of My salvation, I have cried day and night before You, and a little, farther on, I became as it were a man without help, free among the dead. He said not, I became a man without help; but, as it were a man without help. For indeed He was crucified not from weakness, but willingly and His Death was not from involuntary weakness. I was counted with them that go down into the pit. And what is the token? You have put away Mine acquaintance far from Me (for the disciples have fled). Will You show wonders to the dead? Then a little while afterwards: And unto You have I cried, O Lord ; and in the morning shall my prayer come before You. Do you see how they show the exact point of the Hour, and of the Passion and of the Resurrection?
