Matteo 2:20

saying, Arise, and take the young Child and His mother, and go into the land of Israel; for they are dead which sought the young Child's life.

Herod died at Jericho in the year 750 after the founding of Rome. And his son Antipater, heir apparent to the throne, who had inherited his father's cruel disposition, had been put to death at the tyrant's command, five days before he himself yielded up his soul. So they whose murderous designs were most apparent were no longer living. The angel therefore gave Joseph the command to return to the land of Israel.

No immediate danger threatened the Savior's life. No apprehension need be felt regarding His safety. There is nothing, no person to fear: Go! Note again that Matthew always gives to the Christ-child the prominent position to which His divinity entitles Him. He is to be kept foremost in the minds and hearts of all readers.
