Reading the Psalms

The suffering of the Prophet David is, according to the account we have given of the title, a type of the Passion of our God and Lord Jesus Christ. This is why his prayer also corresponds in sense with the prayer of Him Who being the Word was made flesh: in such wise that He Who suffered all things after the manner of man, in everything He said, spoke after the manner of man; and He who bore the infirmities and took on Him the sins of men approached God in prayer with the humility proper to men. This interpretation, even though we be unwilling and slow to receive it, is required by the meaning and force of the words, so that there can be no doubt that everything in the Psalm is uttered by David as His mouthpiece. For he says: Save me O God, by Thy name. Thus prays in bodily humiliation, using the words of His own Prophet, the Only-begotten Son of God, Who at the same time was claiming again the glory which He had possessed before the ages. He asks to be saved by the Name of God whereby He was called and wherein He was begotten, in order that the Name of God which rightly belonged to His former nature and kind might avail to save Him in that body wherein He had been born. (St. Hilary of Poitiers, Homily on Psalm 54, NPNF II.09.04)
