For now will I break his yoke from off thee,.... The Assyrian yoke from off the Jews, who had been obliged to pay tribute, or send presents to the king of Assyria, from the times of Ahaz; and were in bondage, while shut up and besieged by his army, and the country all around laid under contribution; from all which they were delivered when his army was in that dreadful manner destroyed: and will burst thy bonds in sunder; and set thee entirely free from the bondage of the enemy, and all fear of it; a type of that freedom from the yoke of sin, Satan, and the law, which the people of God have by Jesus Christ.
