"Beloved" (Matthew 3:17)

Matthew 3:17: "And see a voice from heaven, saying, This is my beloved Son, in whom I am well pleased" (KJV).

Greek: καὶ ἰδοὺ φωνὴ ἐκ τῶν οὐρανῶν λέγουσα Οὗτός ἐστιν ὁ υἱός μου ὁ ἀγαπητός, ἐν ᾧ εὐδόκησα (WH).

καὶ ἰδοὺ φωνὴ ἐκ τῶν οὐρανῶν λέγουσα· οὗτός ἐστιν ὁ υἱός μου ὁ ἀγαπητός, ἐν ᾧ εὐδόκησα (NA28).

Meyer's NT references Epiphanius (Haer. 30.13) and Justin Martyr (Trypho 88)-Vide Contra Celsum 1.43-48.

Question: Does Matthew 3:17 allude to David's name when the voice from heaven calls Jesus, ὁ ἀγαπητός? In other words, is Jesus implicitly being identified as David's primary offspring here? The Messiah? Compare Matthew 12:18; Mark 12:6.
