And in that day, declares the Lord, you will call me 'My Husband,' and no longer will you call me 'My Baal.' For I will remove the names of the Baals from her mouth, and they shall be remembered by name no more. - Hosea 2:16-17
Baal simply means "lord," "master," or "husband," though Hosea 2:16-17 makes it feel like a less personal title than Ishi. In modern Hebrew, both ishi and baal can describe a husband, but ishi expresses marital relationship and young love, while baali is lordship and fear.
