The writer of Hebrews is offering scriptural proofs of the Son's superiority. Why does he select these quotes? And why is he doing all of this? What drives his interest in setting the superiority of Christ over the angels of God? He has chosen these verses because of two factors. (1) Their identification with Messianic expectations. They exalt Jesus as the fulfillment of the promises made concerning the everlasting Davidic king. (2) The identification of the Messiah with Yahweh. This Davidic king is divine.
