Behold, I will bring again the shadow of the degrees, which hath gone down on the {e} sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it had gone down.

(e) Read 2Ki 20:8.

Jamieson-Fausset-Brown Bible Commentary

8. bring again-cause to return (Jos 10:12-14). In 2Ki 20:9, 11, the choice is stated to have been given to Hezekiah, whether the shadow should go forward, or go back, ten degrees. Hezekiah replied, "It is a light thing (a less decisive miracle) for the shadow to go down (its usual direction) ten degrees: nay, but let it return backward ten degrees"; so Isaiah cried to Jehovah that it should be so, and it was so (compare Jos 10:12, 14).

sundial of Ahaz-Herodotus (2.109) states that the sundial and the division of the day into twelve hours, were invented by the Babylonians; from them Ahaz borrowed the invention. He was one, from his connection with Tiglath-pileser, likely to have done so (2Ki 16:7, 10). "Shadow of the degrees" means the shadow made on the degrees. Josephus thinks these degrees were steps ascending to the palace of Ahaz; the time of day was indicated by the number of steps reached by the shadow. But probably a sundial, strictly so called, is meant; it was of such a size, and so placed, that Hezekiah, when convalescent, could witness the miracle from his chamber. Compare Isa 38:21, 22 with 2Ki 20:9, where translate, shall this shadow go forward, &c.; the dial was no doubt in sight, probably "in the middle court" (2Ki 20:4), the point where Isaiah turned back to announce God's gracious answers to Hezekiah. Hence this particular sign was given. The retrogression of the shadow may have been effected by refraction; a cloud denser than the air interposing between the gnomon and dial would cause the phenomenon, which does not take from the miracle, for God gave him the choice whether the shadow should go forward or back, and regulated the time and place. Bosanquet makes the fourteenth year of Hezekiah to be 689 B.C., the known year of a solar eclipse, to which he ascribes the recession of the shadow. At all events, there is no need for supposing any revolution of the relative positions of the sun and earth, but merely an effect produced on the shadow (2Ki 20:9-11); that effect was only local, and designed for the satisfaction of Hezekiah, for the Babylonian astronomers and king "sent to enquire of the wonder that was done in the land" (2Ch 32:31), implying that it had not extended to their country. No mention of any instrument for marking time occurs before this dial of Ahaz, 700 B.C. The first mention of the "hour" is made by Daniel at Babylon (Da 3:6).

Matthew Henry's Concise Commentary

38:1-8 When we pray in our sickness, though God send not to us such an answer as he here sent to Hezekiah, yet, if by his Spirit he bids us be of good cheer, assures us that our sins are forgiven, and that, whether we live or die, we shall be his, we do not pray in vain. See 2Ki 20:1-11.

Matthew Henry's Whole Bible Commentary

Chapter 38

This chapter proceeds in the history of Hezekiah. Here is, I. His sickness, and the sentence of death he received within himself (v. 1). II. His prayer in his sickness (v. 2, 3). III. The answer of peace which God gave to that prayer, assuring him that he should recover, that he should live fifteen years yet, that Jerusalem should be delivered from the king of Assyria, and that, for a sign to confirm his faith herein, the sun should go back ten degrees (v. 4-8). And this we read and opened before, 2 Ki. 20:1, etc. But, IV. Here is Hezekiah's thanksgiving for his recovery, which we had not before (v. 9-20). To which are added the means used (v. 21), and the end the good man aimed at in desiring to recover (v. 22). This is a chapter which will entertain the thoughts, direct the devotions, and encourage the faith and hopes of those that are confined by bodily distempers; it visits those that are visited with sickness.

Verses 1-8

We may hence observe, among others, these good lessons:-1. That neither men's greatness nor their goodness will exempt them from the arrests of sickness and death. Hezekiah, a mighty potentate on earth and a mighty favourite of Heaven, is struck with a disease, which, without a miracle, will certainly be mortal; and this in the midst of his days, his comforts, and usefulness. Lord, behold, he whom thou lovest is sick. It should seem, this sickness seized him when he was in the midst of his triumphs over the ruined army of the Assyrians, to teach us always to rejoice with trembling. 2. It concerns us to prepare when we see death approaching: "Set thy house in order, and thy heart especially; put both thy affections and thy affairs into the best posture thou canst, that, when thy Lord comes, thou mayest be found of him in peace with God, with thy own conscience, and with all men, and mayest have nothing else to do but to die." Our being ready for death will make it come never the sooner, but much the easier: and those that are fit to die are most fit to live. 3. Is any afflicted with sickness? Let him pray, James 5:13. Prayer is a salve for every sore, personal or public. When Hezekiah was distressed by his enemies he prayed; now that he was sick he prayed. Whither should the child go, when any thing ails him, but to his Father? Afflictions are sent to bring us to our Bibles and to our knees. When Hezekiah was in health he went up to the house of the Lord to pray, for that was then the house of prayer. When he was sick in bed he turned his face towards the wall, probably towards the temple, which was a type of Christ, to whom we must look by faith in every prayer. 4. The testimony of our consciences for us that by the grace of God we have lived a good life, and have walked closely and humbly with God, will be a great support and comfort to us when we come to look death in the face. And though we may not depend upon it as our righteousness, by which to be justified before God, yet we may humbly plead it as an evidence of our interest in the righteousness of the Mediator. Hezekiah does not demand a reward from God for his good services, but modestly begs that God would remembers, not how he had reformed the kingdom, taken away the high places, cleansed the temple, and revived neglected ordinances, but, which was better than all burnt-offerings and sacrifices, how he had approved himself to God with a single eye and an honest heart, not only in these eminent performances, but in an even regular course of holy living: I have walked before thee in truth and sincerity, and with a perfect, that is, an upright, heart; for uprightness is our gospel perfection. 5. God has a gracious ear open to the prayers of his afflicted people. The same prophet that was sent to Hezekiah with warning to prepare for death is sent to him with a promise that he shall not only recover, but be restored to a confirmed state of health and live fifteen years yet. As Jerusalem was distressed, so Hezekiah was diseased, that God might have the glory of the deliverance of both, and that prayer too might have the honour of being instrumental in the deliverance. When we pray in our sickness, though God send not to us such an answer as he here sent to Hezekiah, yet, if by his Spirit he bids us be of good cheer, assures us that our sins are forgiven us, that his grace shall be sufficient for us, and that, whether we live or die, we shall be his, we have no reason to say that we pray in vain. God answers us if he strengthens us with strength in our souls, though not with bodily strength, Ps. 138:3. 6. A good man cannot take much comfort in his own health and prosperity unless withal he see the welfare and prosperity of the church of God. Therefore God, knowing what lay near Hezekiah's heart, promised him not only that he should live, but that he should see the good of Jerusalem all the days of his life (Ps. 128:5), otherwise he cannot live comfortably. Jerusalem, which is now delivered, shall still be defended from the Assyrians, who perhaps threatened to rally again and renew the attack. Thus does God graciously provide to make Hezekiah upon all accounts easy. 7. God is willing to show to the heirs of promise the immutability of his counsel, that they may have an unshaken faith in it, and therewith a strong consolation. God had given Hezekiah repeated assurances of his favour; and yet, as if all were thought too little, that he might expect from him uncommon favours, a sign is given him, an uncommon sign. None that we know of having had an absolute promise of living a certain number of years to come, as Hezekiah had, God thought fit to confirm this unprecedented favour with a miracle. The sign was the going back of the shadow upon the sun-dial. The sun is a faithful measurer of time, and rejoices as a strong man to run a race; but he that set that clock a going can set it back when he pleases, and make it to return; for the Father of all lights is the director of them.
