2 Kings 20:20; 2 Chronicles 32:1–4, 30

2 Kings 20-20

20The other events of Hezekiah’s reign, and all his exploits, and how he made the pool and the conduit and brought the water into the city, are recorded in the Annals of the Kings of Judah.

2 Chronicles 32-1–4

After these faithful deeds, King Sennacherib of Assyria invaded Judah and encamped against its fortified towns with the aim of taking them over. 2When Hezekiah saw that Sennacherib had come, intent on making war against Jerusalem, 3he consulted with his officers and warriors about stopping the flow of the springs outside the city, and they supported him. 4A large force was assembled to stop up all the springs and the wadi that flowed through the land, for otherwise, they thought, the king of Assyria would come and find water in abundance.

2 Chronicles 32-30

30It was Hezekiah who stopped up the spring of water of Upper Gihon, leading it downward west of the City of David; Hezekiah prospered in all that he did.
