IV. That those who stand it out against the gospel of Christ, and continue in league with their idolatries and witchcrafts, shall fall under the wrath of God, and be consumed by it (v. 15): I will execute vengeance in anger and fury upon the heathen (that is, upon heathenism), such as they have not heard; idolatries shall be done away, and idolaters put to shame. I will execute vengeance upon the heathen who have not heard (so some read it), or who would not hear and receive the doctrine of Christ. God will give his Son either the hearts or the necks of his enemies, and make them either his friends or his footstool.
