'Zealous' in the Bible

then a throne shall be established in steadfast love, and one shall sit on it in faithfulness, in the tent of David, judging and seeking justice and zealous for righteousness.

The Lord will go forth like a warrior,He will stir up His zeal like a man of war;He will shout out, yes, He will raise a war cry.He will prevail [mightily] against His enemies.
