At the time of Hezekiah's accession to the throne of Judah, the Assyrian had already carried captive a large number of the children of Israel from the northern kingdom; and a few years after he had begun to reign, and while he was still strengthening the defenses of Jerusalem, the Assyrian besieged and captured Samaria and scattered the ten tribes among the many provinces of the Assyrian realm. The borders of Judah were only a few miles distant, with Jerusalem less than fifty miles away; and the rich spoils to be found within the temple would tempt the enemy to return.
But the king of Judah had determined to do his part in preparing to resist the enemy; and, having accomplished all that human ingenuity and energy could do, he had assembled his forces and had exhorted them to be of good courage. "Great is the Holy One of Israel in the midst of thee" had been the message of the prophet Isaiah to Judah; and the king with unwavering faith now declared, "With us is the Lord our God to help us, and to fight our battles" (Isaiah 12:6; 2 Chronicles 32:8). (Prophets and Kings, 351)
Reflection: Active faith inspires more faith. In preparation for the coming crisis, King Hezekiah encouraged the people to believe in God's Word.
