'Defend' in the Bible

Learn to do good;Seek justice,Reprove the ruthless,Defend the orphan,Plead for the widow.

Your rulers are rebelsAnd companions of thieves;Everyone loves a bribeAnd chases after rewards.They do not defend the orphan,Nor does the widow’s plea come before them.

‘For I will defend this city to save it for My own sake and for My servant David’s sake.’”

I will deliver you and this city from the hand of the king of Assyria; and I will defend this city.”’
