Since we in the United States recently went through the annual ritual of adjusting all of our clocks, watches, and timers, etc. at the start of Fall, I am reminded of two somewhat similar occurrences one can find in the Old Testament history books.
The best treatment of these two narratives is found in Bernard Ramm's valuable book titled The Christian View of Science and Scripture.
The Long Day of Hezekiah
The first is a miracle found in both II Kings 20 and Isaiah 38. Isaiah tells King Hezekiah that he will be cured of an illness and live for another 15 years. We know when Hezekiah died so we can date Isaiah's words to about 702 BC. And to confirm this prophecy, Isaiah tells him, “This is the sign to you from the LORD, that the LORD will do this thing that he has promised: See, I will make the shadow cast by the declining sun on the stairs (acting as a sort of sundial) of Ahaz turn back ten steps.” So the sun turned back on the stairs the ten steps by which it had declined.
In the first place, even a literal understanding of this narrative does not require that you have to believe that the sun moves around the earth just because it says that the sun declined, or was setting, in the sky. It is obviously common phenomenological language employed even today. Now, you can choose to believe that God reversed the rotation of the earth to accomplish the sign. Although God could have certainly done it in this manner, He would have had to simultaneously disrupt most of the laws of physics in order not to destroy every living being on the earth in the process. So it is probably wise to at least consider alternative interpretations. And one is very plausible. There is the known fact that during a total eclipse of the sun (one of which was visible in the Near East in that same year according to astronomers), shadows will momentarily move backwards as the moon goes in front of the sun. I have observed the same phenomenon myself. Ahaz was in bed in an interior room so that he couldn't observe the eclipse, but he could see the shadow on the steps of Ahaz from his bedroom. According to this second explanation, God millennia earlier set the planets, sun and moon in motion so that this sign would appear just when Ahaz needed it. Either way, it is a true miracle.
“The means by which the sign was accomplished is left unstated. Since reversing the rotation of the earth carries with it so many other implications, it seems likely that some sort of refraction of light was involved. 2 Chr. 32:31 seems to imply that it was a local phenomenon.” Wolf agrees with that assessment.
Ramm: “E.W. Maunder considers it to have been a miracle of lighting up the steps, and that is all [perhaps by the Shekinah Glory]. There is no astronomical miracle which will account for it.”
La Sor concludes, “Whether the sun was actually moved backward, or some refraction of its rays caused its shadow to move backward, is a discussion based on attempts to find more than the biblical text actually says.”
The Long Day of Joshua
On the day when the LORD gave the Amorites over to the Israelites, Joshua spoke to the LORD, and he said in the sight of Israel,
“Sun, stand still at Gibeon,
and Moon, in the valley of Aijalon.”
And the sun stood still,
and the moon stopped,
until the nation took vengeance on their enemies.
Is this not written in the Book of Jashar? (Joshua 10:12-13)
This passage follows a literal account in verses 1-11 of the defeat of the Gibeonites aided by a hailstorm sent from God. What are we to make of this passage?
1. Literal interpretation A literal reading would imply that God prolonged the daytime by temporarily slowing down or stopping the motion of the earth and/or the heavenly bodies. Again, because of the worldwide consequences of such an action and the fact that no other culture at that time reported such an event, perhaps we should consider other interpretations.
2. Phenomenological explanation This says that God provided a miracle of refraction to prolong the daylight hours so that the sun appeared to cease moving.
3. Poetic interpretation #1 Let's look at Joshua's words again. There are four reasons to believe that we are talking about figurative or poetic language here rather than literal language: The command is written in typical poetic parallelism as you can see by the way most translations indent the phrases. It also comes from the Book of Jashar, which is a book of poetry, as we know from another long quotation from it found in II Samuel 1. Obviously some of the language here is figurative since it contains a figure of speech known as an apostrophe (addressing inanimate objects or people who aren't present as if they can hear you and respond).
And lastly, we have an exact parallel in the Book of Judges to guide us. There the literal account of a battle in Judges 4 explains that God miraculously sent a thunderstorm to help the Jews to defeat the enemy. This account is then re-told poetically in Judges 5 where Deborah says that the stars fought against the enemy. In the Joshua 10 case, God miraculously sends a hailstorm to aid the Jews according to the literal account in verses 1-11, but the following poetic account in verses 12-13 points to the heavenly bodies as the cause.
4. Poetic interpretation #2 If it is poetry, there is another way of understanding these verses. Joshua is calling on the heavenly bodies to freeze in shocked amazement over the great victory of Israel. Again, there is a parallel found elsewhere in the OT:
“The mountains saw you, and writhed; a torrent of water swept by; the deep gave forth its voice. The sun raised high its hands; the moon stood still in its exalted place at the light of your arrows speeding by, at the gleam of your flashing spear.” (Habakkuk. 3:10-11)
5. Different translations Then there are those scholars who believe that the standard translations are misleading. According to one, Joshua's request for the troop's relief from the sun was granted through a thunderstorm, which refreshed the army so that they were able to accomplish a day's march in half a day. Therefore, the translation should read, “The sun ceased to shine.”
Or there is the possibility that Joshua is actually calling down a curse on the sun and moon gods of Gibeon to “cease” from helping the Gibeonites.
I will close with a few of the comments Kaiser offers on this problem: First, he points out that there would have been no way of actually discerning whether the sun stood still in the sky because of the violent hailstorm which was occurring at the time (see Josh. 10:11). Therefore it is best to take the word dom in v. 13 to mean the sun 'was dumb' or 'silent' during the storm, indicating that the heat of the sun no longer bothered Israel's troops so that “the coolness brought by the storm relieved the men and permitted them to go on fighting and marching for a total of more than eighteen hours.” Kaiser discounts other suggested phenomena such as an unusual refraction of the sun's rays or the effect of a passing comet or meteorite since “usually these types of astronomical events are of short duration.”
Final Comments
By the way, all of the above explanations come from conservative Christian sources. They are not just attempts to explain away the miracle, just to explain it.
As Ramm rightly concludes, “All we need to assert is that evangelicalism is not embarrassed for want of a rationale of the long day of Joshua.”
In closing, you may happen to run across an account on the internet that says NASA scientists used their supercomputer to calculate the positions of all the stars and planets throughout the ages and came up with one day and a few hours missing in time, thus proving the existence of these two miracles. Ignore it. It is an urban Christian legend that has been around for decades and thoroughly debunked many times.
