'Fighting' in the Bible

And they said, “This is blood! Clearly the kings have fought together, and have killed one another. Now then, Moab, to the spoil [and the plunder of the dead soldiers]!”

So the Rabshakeh returned and found the king of Assyria fighting against Libnah [a fortified city of Judah]; for he had heard that the king had left Lachish.
