Isaiah 42:13

The Lord, in carrying out His counsel of salvation, shall go forth as a mighty man, like a hero; He shall stir up jealousy, the indignation and fury in His own heart, like a man of war, an invincible warrior; He shall cry, yea, roar, with a fearful battle-cry; He shall prevail against His enemies, boasting of His victory over all His enemies. The entire section is built up so that there can he no question of Jehovah's final triumph. The Lord now takes up His proclamation in person once more.
