The LORD will go forth like a warrior, He will arouse His zeal like a man of war. He will utter a shout, yes, He will raise a war cry. He will prevail against His enemies. (Isaiah 42:13)

mighty man . . . man of war. As a mighty warrior, the Lord will work through his Servant to overcome all enemies (John MacArthur)

He will appear in his power and glory more than ever. So he did in the preaching of his gospel, in the divine power and energy which went along with it, and in the wonderful success it had in the pulling down of Satan’s stronghold. (Matthew Henry)
