King James Version (KJV)
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. {prevail: or, behave himself mightily}
Modern English
Yahweh 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.
Hebrew
