Instead of remonstrating with the Angel about suggesting he appear to Herod, for real, and scare him out of this idea, or maybe send his mate, the not-surreal but very real Angel of Death, the one from off of the Passover, Joseph got up, for he always followed his dreams, even when they involved supernatural messengers from outer space (if not there, then where?), and even when he was asleep, for he was a somnambulist (and not just a carpenter).
He (Joseph) took the child and his mother (that one) during the night (for he was still asleep) and left for Egypt, where he stayed until the death of Herod.
And so was fulfilled what the Lord had said through the prophet: “Out of Egypt I called my son,” which was not in the least contrived by Matthew (the author of this Gospel, i.e. me) to prove that he (the baby) was the Messiah, as a way of tricking credulous Jews to convert to the early church.
