Around the time when Sennacherib king of Assyria attacked Judah, king Hezekiah contracted a life-threatening disease. Hezekiah’s sickness may have been the result of spiritual circumstances connected with his removal of the high places and images used in idolatry (2 Kings 18:4). Isaiah the prophet came to Hezekiah, “and said unto him, Thus saith the LORD, Set thine house in order: for thou shalt die, and not live” (Isaiah 32:1).

Hezekiah’s response to Isaiah’s declaration indicated that Hezekiah was a man of faith. He believed that prayer could change the outcome of his situation. It says in Isaiah 38:2-3, “Then Hezekiah turned his face toward the wall, and prayed unto the LORD, and said, Remember now, O LORD, I beseech thee, how I have walked before thee in truth with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore.”

Hezekiah poured out his heart to the LORD in a very real and personal way. He didn’t ask the LORD for anything, Hezekiah merely wanted the LORD to know how he felt about the news he had just received. At the time Hezekiah was told he was going to die, he was about 37 or 38 years old, the prime of life for a man living in that time period.

Hezekiah’s prayer received a response, but the LORD didn’t speak to him directly. “Then came the word of the LORD to Isaiah, saying, Go and say to Hezekiah, Thus saith the LORD, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will add unto thy days fifteen years” (Isaiah 38;4-5). The specification of Hezekiah’s time of death meant that he was receiving a divinely appointed extension to his life span, an unusual blessing from the LORD.

It is likely that by changing the time of Hezekiah’s death, God allowed Hezekiah’s life to change the course of history. A connection was made between the extension of Hezekiah’s life and the deliverance of Jerusalem out of the hand of the king of Assyria (Isaiah 38:5-6). After Hezekiah recovered, he received a visit from the king of Babylon (Isaiah 39:1) to whom he revealed all his kingdom’s treasures (Isaiah 39:4). As a result of this mistake, It says in Isaiah 39:5-6:

Then said Isaiah to Hezekiah, Hear the word of the LORD of hosts: Behold, the days will come, that all that is in thine house, and that which thy fathers have laid up in store until this day, shall be carried to Babylon: nothing shall be left, saith the LORD.
