Mt.27:26 (“My God..why have you forsaken me?) Jesus is reciting Psalm 22 on the Cross, which ends in triumph and assurance! In times of trouble, He (and we!) turn to scripture! No despair!
Luke 23:44-46 (“Into Your hands I commend my spirit.”) Jesus is reciting Psalm 31 from the Cross, which also ends in assurance. No despair!
Some other Psalms Jesus quoted in the Gospels and their parallels:
Ps 8:3-Mt 21:16
Ps 35:19-Jn 15:18-25
Ps 110:1-Mt 22:41-45
Ps 118:22-Mt-21:42
Jesus quoted from the Psalms more than any other book.
In Luke 24:44-45 it says Jesus explained the scriptures to them “that everything written about me in the law of Moses and in the prophets and PSALMS must be fulfilled.”
