What Hezekiah Did
Thirteenth king of Judah: purged the idolatry of his father Ahaz, cleansed and reopened the temple, kept a Passover to which all Israel was invited, destroyed the brasen serpent when it became an idol, and in the Assyrian invasion saw Jerusalem delivered by the angel of the Lord; his life was lengthened fifteen years.
Accomplished for Good
"He trusted in the LORD God of Israel; so that after him was none like him among all the kings of Judah" (2 Kings 18:5); in the siege he spread Sennacherib’s letter before the LORD and prayed (2 Kings 19:14-19); in sickness he wept and prayed and was heard.
Mistakes and Failures
When the envoys of Babylon came, he showed them all the treasures of his house with pride, and received Isaiah’s word that all would be carried to Babylon (2 Kings 20:13-18); his son Manasseh undid his reforms and became Judah’s most wicked king.
From Easton’s Bible Dictionary (1897)
the thirteenth king of Judah, son of Ahaz, who began to reign at twenty-five and reigned twenty-nine years in Jerusalem (2 Kings 18:1–2). “He trusted in the LORD God of Israel; so that after him was none like him among all the kings of Judah, nor any that were before him” (2 Kings 18:5). He removed the high places, brake the images, cut down the groves, and brake in pieces the brasen serpent Moses had made, because Israel burned incense to it (18:4). He kept the Passover with an invitation to all Israel (2 Chronicles 30), cleansed the temple, and restored its worship. When Sennacherib of Assyria invaded and Rabshakeh blasphemed at the wall, Hezekiah rent his clothes, went into the house of the LORD, and prayed; that night the angel of the LORD smote 185,000 in the Assyrian camp (2 Kings 19). In his sickness unto death he wept and prayed, and God added fifteen years to his life, turning back the shadow on the dial of Ahaz as the sign (2 Kings 20; Isaiah 38).
