"Deliver, O God, my soul from the sword: my only one from the hand of the dog. Save me from the lion's mouth; and my lowness from the horns of the unicorns. I will declare thy name to my brethren: in the midst of the Church will I praise thee. Ye that fear the Lord, praise him: all ye the seed of Jacob, glorify him. Let all the seed of Israel fear him: because he hath not slighted nor despised the supplication of the poor man. Neither hath he turned away his face from me: and when I cried to him he heard me.
Hence Jesus Christ, by saying "My God, my God, why have you forsaken me," was not actually declaring that God had forsaken Him, but rather firmly and finally establishing His unique claim to be the one and only Messias and Redeemer, who the prophets of old had always known would be both God and man.
Micheas 7:7: "But I will look towards the Lord, I will wait for God my Saviour: my God will hear me."
Daniel 9:26: "Christ shall be slain"
