2 Chronicles 32:1-8

After these acts of faithfulness Sennacherib king of Assyria came and invaded Judah and besieged the fortified cities, and thought to break into them for himself. Now when Hezekiah saw that Sennacherib had come and that he intended to make war on Jerusalem, he decided with his officers and his warriors to cut off the supply of water from the springs which were outside the city, and they helped him. So many people assembled and stopped up all the springs and the stream which flowed through the region, saying, “Why should the kings of Assyria come and find abundant water?” And he took courage and rebuilt all the wall that had been broken down and erected towers on it, and built another outside wall and strengthened the Millo in the city of David, and made weapons and shields in great number. He appointed military officers over the people and gathered them to him in the square at the city gate, and spoke encouragingly to them, saying, “Be strong and courageous, do not fear or be dismayed because of the king of Assyria nor because of all the horde that is with him; for the one with us is greater than the one with him. With him is only an arm of flesh, but with us is the LORD our God to help us and to fight our battles.” And the people relied on the words of Hezekiah king of Judah.
