Background to Psalms 69

What is the relationship between Jesus and the Psalms? 

Did Jesus get his idea of who he was from them, or did he know intuitively who he was and then reveal to his disciples what the ultimate meaning of these psalms is? New Testament scholar Ben Witherington III is not sure: “It is hard to say whether Jesus’ self-understanding affected more the way he looked at these texts, or the texts themselves affected more how Jesus viewed himself and his mission.”
One view current is that if we take seriously the humanity of Jesus and his participation in the way human beings learn, it is possible to think that Jesus came to understand himself at least partly through the ability of his own HolySpirit-inspired, sin-free mind to read the Scriptures and to understand them like no one before him.

It is striking that when Jesus turned from those around him and to his Father God, he chose psalms as his voice. 1-3 found here.

4. “Eloi, Eloi, lema sabachthani,” that is, “My God, my God, why have you forsaken me?” (Mark 15:34 and Matthew 27:46, quoting Psalm 22:1). 

5. “I am thirsty” (John 19:28, quoting Psalm 69:21; cf. 22:15). 

6. “It is finished” (John 19:30, quoting Psalm 22:31). 

7. “Father, into your hands I commend my spirit” (Luke 23:46, alluding to Psalm 31:5).

Consider the view of Jesus as the living word of God, taking seriously the divinity of Jesus, Word made flesh. Does it change your view of the relationship between Jesus and the Psalms?
