The other events of the rule of Hezekiah are written down. That includes how he made the pool and the tunnel. He used them to bring water into Jerusalem. Everything he accomplished is written in the official records of the kings of Judah.
Hezekiah blocked up the upper opening of the Gihon spring. He directed the water to flow down to the west side of the City of David. He had success in everything he did.
Next to Shallun, Nehemiah made some repairs. He was the son of Azbuk. Nehemiah ruled over half of the territory where Beth Zur was located. He repaired the wall up to the part that was across from the tombs of David. He repaired it all the way to the man-made pool and the House of the Heroes.
