And it shall be in that day that the burden of the Assyrian shall depart from off your shoulder, and his yoke from off your neck. And on that day his load shall be rolled off your shoulder, And his yoke from your neck, and the yoke chafe be healed. And it shall come to pass in that day, that his burden shall be taken from off thy shoulder, and his yoke from off thy neck, and the yoke shall be destroyed because of the anointing. And with that, thy shoulder will be eased of the burden, the yoke will fall from thy neck, yoke that has gone rotten for want of oil. On that day God will end the bondage of his people.
