'Battles' in the Bible

Now the words of Rehoboam [from] the first to the last, are they not written in the chronicles of Shemaiah the prophet and Iddo the seer as a record? And [there were] battles [between] Rehoboam and Jeroboam all their days.

And the rest of the matters of Jotham, and all his battles, and his ways, lo, they are written on the book of the kings of Israel and Judah.

With him is an arm of flesh; but with us is the LORD our God to help us, and to fight our battles. And the people rested themselves upon the words of Hezekiah king of Judah.
