Isaiah 42:13

This verse gives the reason for the praise just called for. Isaiah gloried in the fact that Yahweh would one day arise as a mighty warrior to overcome His enemies. He did this when He moved Cyrus to allow the Israelites to return to their land. He did it more mightily when He sent Messiah to accomplish redemption. And He will do it most dramatically when Messiah comes back to the earth to defeat His enemies at Armageddon (Revelation 14:14-20; Revelation 19:17-19).
