Luke 2:39

If the wise men, mentioned Matthew 2:1, had been with Herod before this time, it is more than probable that Herod would have made an end of Christ at this time, therefore certainly it was after this time. Luke saith nothing of what we have Matthew 2:13-23, of Joseph going into Egypt upon the admonition of the angel, nor his coming back; but both Matthew and Luke agree in their dwelling at Nazareth, which he calleth their own city, for there Joseph dwelt, Luke 2:4. How after this the wise men came to find him at Bethlehem, Matthew 2:1, the Scripture hath not told us. It is very idle for any to say Joseph dwelt there, for then he would not have taken up his inn there, nor been put to such a stress as to have his wife bring forth in a stable; besides, it is apparent from Luke 2:4 and this verse, and from Matthew 2:23, that he dwelt at Nazareth. God, who ordered the motion of the wise men, and their instructions to be sent to Bethlehem to look for Christ, could easily find Joseph some business to be done there at that time, whether some business of his trade, or some visit to his friends, we cannot say.
