Matthew 2:13

The angel. — Better, an angel. The interval of time between the departure of the Magi and Joseph’s dream is not specified. Probably it was very short. As with the Magi, the dream may have come as an echo of his waking thoughts, an answer to the perplexities with which their visit and the other wonders of the time had filled his spirit.

Flee into Egypt. — The nearness of Egypt had always made it a natural asylum for refugees from Palestine. So Jeroboam had found shelter there (1 Kings 11:40), and at a later date, Johanan the son of Kareah and his companions had fled thither from the face of Nebuchadnezzar (Jeremiah 43:7). The number of Jews who were settled in Alexandria and other cities of Egypt had probably made the step still more common during the tyranny of Herod’s later years.
