Isaiah 42:13

The Lord goes forth like a mighty one; He stirs up His zeal like a warrior. He shouts; yes, He roars in triumph over His enemies:

The Lord shall go forth as a mighty man, he shall stir up jealousy like a man of war: he shall cry, yea, roar; he shall prevail against his enemies.

Note prevail: or, behave himself mightily

The Lord will go out like a mighty man. He will stir up zeal like a man of war. He will raise a war cry. Yes, he will shout aloud. He will triumph over his enemies.

Jehovah will go forth as a mighty man; he will stir up his zeal like a man of war: he will cry, yea, he will shout aloud; he will do mightily against his enemies.
