'Battle' in the Bible

about forty thousand ready armed for war passed over before Jehovah unto battle, to the plains of Jericho.

And it came to pass, when the king of Ai saw it, that they hasted and rose up early, and the men of the city went out against Israel to battle, he and all his people, at the time appointed, before the Arabah; but he knew not that there was an ambush against him behind the city.

There was not a city that made peace with the children of Israel, save the Hivites the inhabitants of Gibeon: they took all in battle.

For it was of Jehovah to harden their hearts, to come against Israel in battle, that he might utterly destroy them, that they might have no favor, but that he might destroy them, as Jehovah commanded Moses.
