In fact, it took them about two years to make the trek from their homeland to Judea, when they approached Herod.
Scholars who interpret Matthew as casting Jesus in the role of being a second argue that, like Moses, the infant Jesus is saved from a murderous tyrant; and he flees the country of his birth until his persecutor is dead and it is safe to return as the savior of his people.
No wonder they clamored for Jesus to topple Rome, just as the Red Sea had toppled the Egyptians.
My interest however, lies in the missing years between childhood and adulthood.
