'Wars' in the Bible

And the acts of Rehoboam, first and last, are they not written in the words of Shemaiah the prophet, and of Iddo the seer, in the genealogical registers? And there were wars between Rehoboam and Jeroboam continually.

For the eyes of Jehovah run to and fro through the whole earth, to shew himself strong in the behalf of those whose heart is perfect toward him. Herein thou hast done foolishly; for from henceforth thou shalt have wars.

And the rest of the acts of Jotham, and all his wars, and his ways, behold, they are written in the book of the kings of Israel and Judah.
