Micah 5:3

Therefore, because Israel, the people of the Lord, is to be redeemed not by his own power, but by the gracious gift of the Messiah, will He give them up, the Lord giving the covenant nation into the hands of the enemy, until the time that she which travaileth hath brought forth, until the Messiah would have been born; then the remnant of His brethren shall return unto the children of Israel, for at that time the Lord would bring together from the various nations of the world those whom He intended to add to His true Israel, to His spiritual nation. The humiliation of the house of David and of Israel had been included in the plan of God, but the final result would be that the Messiah, like His ancestor David, would go forth from the humble city of Bethlehem. To this end it was necessary for the people to remain under the rule of the enemies.
