2 Chronicles 32:20-30

20 Then Hezeki'ah the king and Isaiah the prophet, the son of Amoz, prayed because of this and cried to heaven.
21 And the LORD sent an angel, who cut off all the mighty warriors and commanders and officers in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he came into the house of his god, some of his own sons struck him down there with the sword.
22 So the LORD saved Hezeki'ah and the inhabitants of Jerusalem from the hand of Sennach'erib king of Assyria and from the hand of all his enemies; and he gave them rest on every side.
23 And many brought gifts to the LORD to Jerusalem and precious things to Hezeki'ah king of Judah, so that he was exalted in the sight of all nations from that time onward.
24 In those days Hezeki'ah became sick and was at the point of death, and he prayed to the LORD; and he answered him and gave him a sign.
25 But Hezeki'ah did not make return according to the benefit done to him, for his heart was proud. Therefore wrath came upon him and Judah and Jerusalem.
26 But Hezeki'ah humbled himself for the pride of his heart, both he and the inhabitants of Jerusalem, so that the wrath of the LORD did not come upon them in the days of Hezeki'ah.
27 And Hezeki'ah had very great riches and honor; and he made for himself treasuries for silver, for gold, for precious stones, for spices, for shields, and for all kinds of costly vessels;
28 storehouses also for the yield of grain, wine, and oil; and stalls for all kinds of cattle, and sheepfolds.
29 He likewise provided cities for himself, and flocks and herds in abundance; for God had given him very great possessions.
30 This same Hezeki'ah closed the upper outlet of the waters of Gihon and directed them down to the west side of the city of David. And Hezeki'ah prospered in all his works.
