Gihon Springs

2CH 32:30 It was Hezekiah who blocked the upper outlet of the Gihon spring and channeled the water down to the west side of the City of David. He succeeded in everything he undertook. 

 
 2CH 33:10 The LORD spoke to Manasseh and his people, but they paid no attention. 11 So the LORD brought against them the army commanders of the king of Assyria, who took Manasseh prisoner, put a hook in his nose, bound him with bronze shackles and took him to Babylon. 12 In his distress he sought the favor of the LORD his God and humbled himself greatly before the God of his fathers. 13 And when he prayed to him, the LORD was moved by his entreaty and listened to his plea; so he brought him back to Jerusalem and to his kingdom. Then Manasseh knew that the LORD is God.

    2CH 33:14 Afterward he rebuilt the outer wall of the City of David, west of the Gihon spring in the valley, as far as the entrance of the Fish Gate and encircling the hill of Ophel; he also made it much higher. He stationed military commanders in all the fortified cities in Judah.
