'Battles' in the Bible

He left those nations simply because he wanted to teach the subsequent generations of Israelites, who had not experienced the earlier battles, how to conduct holy war.

But Joash said to all those who confronted him, "Must you fight Baal's battles? Must you rescue him? Whoever takes up his cause will die by morning! If he really is a god, let him fight his own battles! After all, it was his altar that was pulled down."
