Matthew Poole and continuators on Matthew 2:20

20 Saying arise, and take the young child, and his mother and go into the land of Israel, for they are dead who sought the young childs life.

That is, as some say, within three or four Months (for Herod they say no longer out-lived this bloody Act) and if we may believe Historians, he was in his Death, made a dreadful Example of Divine Vengeance, but we cannot assert the just time how long he out-lived this bloody Act; when he was dead, God who had promised Ioseph v. 13. to tell him by an Angel (as before) let Ioseph know he might safely return: It is probable this Apparition was not immediately upon the Death of Herod, for Archelaus was reigning, who must be allowed some time to go to Rome, and to have this Dignity conferred on him, but soon after he was Dead, this Apparition was, with a Command to him, to return into the Land of Israel, to which he soon yieldeth Obedience.
