In Matthew 17 Jesus unveiled his glory at the transfiguration where “his face shone like the sun, and his clothes became white as light” (Matt. 17:2). Peter, James, and John witnessed this event.
Sight was followed by sound. A voice from an enveloping cloud said, “This is my beloved Son, with whom I am well pleased; listen to him” (Matt. 17:5). Here the Father spoke about the Son, and each phrase alluded to the Old Testament.
“This is my beloved Son”–an allusion to Psalm 2:7. Psalm 2 speaks of the king whom Yahweh established on Zion (2:6). And the Lord says to the king, “You are my Son” (2:7).
“with whom I am well pleased”–an allusion to Isaiah 42:1. Isaiah 42 speaks of the Servant figure who will later be described as the iniquity-bearer in Isaiah 53. God says, “Behold my servant, whom I uphold, my chosen, in whom my soul delights” (Isa. 42:1).
“listen to him”–an allusion to Deuteronomy 18:15. Deuteronomy 18 foretells a prophet whom God would one day raise up. Moses says, “The LORD your God will raise up for you a prophet like me from among you, from your brothers–it is to him you shall listen” (Deut. 18:15).
In the Father’s own words of confirmation at the transfiguration, Jesus was the beloved King, the pleasing Servant, and the anticipated Prophet.
