This was to fulfill
What had been spoken
By the Lord,
Through the prophet.
‘Out of Egypt,
I have called my son.’”
ἵνα πληρωθῇ τὸ ῥηθὲν ὑπὸ κυρίου διὰ τοῦ προφήτου λέγοντος
Ἐξ Αἰγύπτου ἐκάλεσα τὸν υἱόν μου.
Matthew explained that the reason for this trip to Egypt was to fulfill (ἵνα πληρωθῇ) a divine prophecy. The word of the Lord (τὸ ῥηθὲν ὑπὸ κυρίου) had spoken this prophecy though the prophet Hosea, chapter 11:1 (διὰ τοῦ προφήτου λέγοντος), although Hosea was not explicitly mentioned here. Just as Yahweh, the Lord, had originally called his child Israel from Egypt as in Hosea, so too, the Lord, the Father, would again call his son, this child, from Egypt (Ἐξ Αἰγύπτου ἐκάλεσα τὸν υἱόν μου). In other words, Matthew makes it sound like this expediency to get away from Herod was set up to fulfill the Lord’s prophecy in Hosea.
