You may wonder, Can one person make a difference in the world? Is it possible to change the course of history? Hezekiah, king of Judah reigned from 715 B.C. to 686 B.C. during a critical time period when the Assyrian empire was spreading rapidly throughout the middle east. In 722 B.C., the northern kingdom of Israel was conquered by Sargon II, king of Assyria and its people were taken into captivity. In 701 B.C., Sennacherib, king of Assyria attacked Jerusalem, the capital of the nation of Judah. Shortly before this, Sennacherib led a campaign against the strongholds of Judah and took them (2 Kings 18:14).

It says in 2 Kings 20:1 that “in those days was Hezekiah sick unto death. And the prophet Isaiah the son of Amoz came to him, and said unto him, Thus saith the LORD, Set thine house in order: for thou shalt die and not live.” Isaiah’s use of the words “thus saith the LORD” indicated that God had sovereignly ordained Hezekiah’s death. In response to the news, Hezekiah cried out to the LORD. It says in 2 Kings 20:2-3, “Then he turned his face to the wall, and prayed unto the LORD, saying, I beseech thee, O LORD, remember now how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore.”

In the early years of his reign, Hezekiah had instituted many reforms in Jerusalem in order to counteract the evil behavior of his father, king Ahaz (2 Kings 18:4). Much to his credit, it says of Hezekiah in 2 Kings 18:5, “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.” Hezekiah’s relationship with the LORD gave him the confidence he needed to ask God to change his mind. It says in 2 Kings 20:4-6:

And it came to pass, afore Isaiah was gone out into the middle court, that the word of the LORD came to him, saying, Turn again, and tell Hezekiah the captain of my people, Thus saith the LORD, the  God of David thy father, I have heard thy prayer, I have seen thy tears:  behold, I will heal thee: on the third day thou shalt go up unto the house of the LORD. And I will add unto thy days fifteen years; and I will deliver thee and this city out of the hand of the king of Assyria; and I will defend this city for mine own sake, and for my servant David’s sake.

Based on the LORD’s message to Hezekiah, “I will deliver thee and this city out of the hand of the king of Assyria” (2 Kings 20:6), it appears that the  LORD intended to give Sennacherib victory over Jerusalem after Hezekiah’s death. It could be that the LORD planned Hezekiah’s death in order to spare him from going into captivity in Assyria. Whatever his intent, the LORD saw Hezekiah’s sincerity and decided to deliver Jerusalem from the Assyrian army instead.

An interesting aspect of Hezekiah’s situation was that he asked for a sign that the LORD would actually do what he said he would. “‘Signs’ are attestations of the validity of a prophetic message” (226). In essence, Hezekiah’s request for a sign meant that he doubted what Isaiah said was true. Perhaps, because he knew he could not defeat the Assyrian army. Isaiah gave Hezekiah two options. “And Isaiah said, This sign shalt thou have of the LORD, that the LORD will do the thing that he hath spoken: shall the shadow go forward ten degrees, or go back ten degrees?” (2 Kings 20:9).

The only miracle recorded in the Bible comparable to what Isaiah suggested the LORD would do for a sign to Hezekiah was when the sun stood still while Joshua and his army fought the Amorites. In that instance, it says, “the sun stood still in the midst of heaven, and hasted not to go down about a whole day” (Joshua 10:13). Since we know now that the sun does not revolve around the earth, but the earth around the sun, what actually happened was the earth stopped spinning for about 24 hours.

In Hezekiah’s case, what Isaiah was suggesting was that the LORD could make the earth rotate in the opposite direction, equivalent to 10 degrees of movement, so that the shadow would go backward instead of forward as it usually did. Based on what we know today, this was scientifically impossible. The amount of time that would have been gained or lost would have been about 20-40 minutes, a somewhat insignificant amount of time compared to the whole day that Joshua gained. Therefore, the evidence of the shadow made it possible to verify that is actually happened.

Hezekiah’s response indicated that he wanted God to do the impossible. “And Hezekiah answered, It is a light thing for the shadow to go down ten degrees: nay, but let the shadow return backward ten degrees. And Isaiah the prophet cried unto the LORD: and he brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz” (2 Kings 20:10-11).
