'Face to face' in the Bible

Then Amaziah sent messengers to Jehoash the son of Jehoahaz the son of Jehu king of Israel, saying, "Come let us meet {face-to-face}."

But Amaziah would not listen, so Jehoash king of Israel went up and they met face-to-face, he and Amaziah king of Judah, at Beth-Shemesh which belongs to Judah.
