'Battlefield' in the Bible

After King Amaziah of Judah consulted with his advisers, he sent this message to the king of Israel, Joash son of Jehoahaz, the son of Jehu, "Come, face me on the battlefield."

So King Joash of Israel attacked. He and King Amaziah of Judah faced each other on the battlefield in Beth Shemesh of Judah.

He executes judgment against the nations; he fills the valleys with corpses; he shatters their heads over the vast battlefield.
