'Corner gate' in the Bible

And Joash the king of Israel took Amaziah king of Judah, the son of Joash, the son of Jehoahaz, at Beth-shemesh, and brought him to Jerusalem, and broke down the wall of Jerusalem from the gate of Ephraim to the corner gate, four hundred cubits.

Moreover Uzziah built towers in Jerusalem at the corner gate, and at the valley gate, and at the turning of the wall, and fortified them.
