The Book of Isaiah

Chapter 1 V.1 Part 5.7

One of the most striking instances recorded in Holy Scripture of the interruption, or rather reversal, of the working of a natural law; is the going back of the shadow on the dial of Ahaz at the time of Hezekiah’s recovery from his illness. The record of the incident is as follows. Isaiah was sent to Hezekiah in his sickness, to say:

“Thus saith Yahweh, 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 Yahweh. …. And Hezekiah said unto Isaiah, What shall be the sign that Yahweh will heal me, and that I shall go up unto the house of Yahweh the third day? And Isaiah said, This shall be the sign unto thee from Yahweh, that Yahweh will do the thing that he hath spoken: shall the shadow go forward ten steps, or go back ten steps? And Hezekiah answered, It is a light thing for the shadow to decline ten steps: nay, but let the shadow return backward ten steps. And Isaiah the prophet cried unto Yahweh; and he brought the shadow ten steps backward, by which it had gone down on the dial of Ahaz” (2Ki 20:5-11). And in Isa 38:8, it is said, “Behold, I will cause the shadow on the steps, which is gone down on the dial of Ahaz with the sun, to return backward ten steps. So the sun returned ten steps on the dial whereon it was gone down.”

The Sign a Real Miracle:

The first and essential point to be noted is that this was no ordinary astronomical phenomenon, nor was it the result of ordinary astronomical laws then unknown. It was peculiar to that particular place, and to that particular time; otherwise we should not read of “the ambassadors of the princes of Babylon, who sent …. to inquire of the wonder that was done in the land” (2Ch 32:31). It is impossible, therefore, to accept the suggestion that the dial of Ahaz may have been improperly constructed, so as to produce a reversal of the motion of the shadow at certain times. For such a maladjustment would have occasioned the repetition of the phenomenon every time the sun returned to the same position with respect to the dial. The narrative, in fact, informs us that the occurrence was not due to any natural law, known or unknown, since Hezekiah was given the choice and exercised it of his own free will, as to whether a shadow should move in a particular direction or in the opposite. But there are no alternative results in the working of a natural law. “If a state of things is repeated in every detail, it must lead to exactly the same consequences.” The same natural law cannot indifferently produce one result, or its opposite. The movement of the shadow on the dial of Ahaz was, therefore, a miracle in the strict sense of the term. It cannot be explained by the working of any astronomical law, known or unknown. We have no information as to the astronomical conditions at the time; we can only inquire into the setting of the miracle.

Time of Day of the Miracle:

At certain times of the day the shadow of some object fell upon this staircase, and we learn from both 2Ki and Isa that this shadow had already gone down ten steps, while from Isa we learn in addition that the sun also was going down. The miracle therefore took place in the afternoon, when the sun moves on its downward course, and when all shadows are thrown in an easterly direction. We are not told what was the object that cast the shadow, but it must have stood to the west of the staircase, and the top of the staircase must have passed into the shadow first, and the foot of the staircase have remained longest in the light. The royal palace is understood to have been placed southeast of the Temple, and it is therefore probable that it was some part of the Temple buildings that had cast its shadow down the stairway in full view of the dying king, as he lay in his chamber. If the afternoon were well advanced the sun would be moving rapidly in altitude, and but little in azimuth; or, in other words, the shadow would be advancing down the steps at its quickest rate, but be moving only slowly toward the left of those who were mounting them. It may well have been the case, therefore, that the time had come when the priests from Ophel, and the officials and courtiers from the palace, were going up the ascent into the house of the Lord to be present at the evening sacrifice; passing from the bright sunshine at the foot of the stairs into the shadow that had already fallen upon the upper steps. The sun would be going straight down behind the buildings and the steps already in shadow would sink into deeper shadow, not to emerge again into the light until a new day’s sun had arisen upon the earth.
