5:15 And I will execute vengeance in anger and fury upon the heathen, {l} such as they have not heard.
(l) It will be so terrible that nothing like it has been heard of.
5:15 Have not heard - In an unprecedented manner. Christ will give his Son either the hearts or necks of his enemies, and make them either his friends or his footstool.
5:7-15 The remnant of Israel, converted to Christ in the primitive times, were among many nations as the drops of dew, and were made instruments in calling a large increase of spiritual worshippers. But to those who neglected or opposed this salvation, they would, as lions, cause terror, their doctrine condemning them. The Lord also declares that he would cause not only the reformation of the Jews, but the purification of the Christian church. In like manner shall we be assured of victory in our personal conflicts, as we simply depend upon the Lord our salvation, worship him, and serve him with diligence.
