This passage describes the Flight into Egypt, where an angel warns Joseph in a dream to flee with Mary and baby Jesus to Egypt to escape King Herod, who wants to kill Jesus; they stay until Herod dies, fulfilling prophecy, and then return to Israel, settling in Nazareth after being warned again, fulfilling another prophecy about the "Nazarene". This passage highlights God's protection, the fulfillment of Old Testament prophecies (Hosea 11:1 and Jeremiah 31), and links Jesus to Israel's history as a divine messenger.
