Then Amaziah sent messengers to Jehoash, the son of Jehoahaz son of Jehu, king of Israel, saying, Come, let us look one another in the face. 2 Kings 14:8
"During excavations at the Givati Parking Lot in Jerusalem, in the area between the Ophel and the City of David, archaeologists discovered fascinating channels that they believe were related to theTemple or royal palace during the reigns of Joash and Amaziah in the ninth century B.C. There is just one problem: They have no idea what they were used for,
Consisting of two separate installations, 32 feet apart, the channels are cut into the bedrock of the hillside. The first installation consists of nine channels, smoothed on the inside. The second installation includes at least five channels that were related in some way to an industrial process carried out in the first installation,
The mystery only grew deeper when a second installation was found to the south. “This [second] installation consists of at least five channels that transport liquids,” said Yuval Gadot of Tel Aviv University. “Despite some differences in the way the channels were hewn and designed, it is evident that the second installation is very similar to the first. This time, we also managed to date when the facility fell out of use, at the end of the ninth century B.C. during the days of the Biblical kings of Judah, Joash and Amaziah. We assume that the two installations may have been used in unison.” BAR
