Isa 38:8

“We find in the commentaries, written by our predecessors, that day had thirty-two hours. For when the sun had run its course, and reached the tenth hour, and the shadow had gone down by the ten degrees in the house of the temple, the sun turned back again by the ten degrees, according to the word of the Lord, and there were thus twenty hours. And again, the sun accomplished its own proper course, according to the common law, and reached its setting. And thus there were thirty-two hours.”

“For Hezekiah's sake the sun turned back, but for Christ the sun was eclipsed. The sun did not simply retrace its path for Christ but was completely eclipsed. This shows the difference between Hezekiah and Jesus. The former's prayer resulted in the canceling of God's decree. But does not Jesus forgive sins? Repent, shut your door, and pray to be forgiven. Pray that Christ may remove you from the burning flames, for confession has power even to quench fire, power even to tame lions.”

“Behold I return the shade backwards ten steps which it went down. the shade of the steps A sort of steps made opposite the sun to determine the hours of the day, like the clocks (horloge in French) that craftsmen make (sectarians make [Parshandatha]). that it went down It hastened to go down, and the day was shortened by ten hours on the day Ahaz died, in order that they should not eulogize him, and now they went backwards on the day Hezekiah recovered, and ten hours were added to the day.”

“The writing of Hezekiah king of Judah,.... The Septuagint and Arabic versions call it a "prayer": but the Targum, much better, "a writing of confession;'' in which the king owns his murmurings and complaints under his affliction, and acknowledges the goodness of God in delivering him out of it: this he put into writing, as a memorial of it, for his own benefit, and for the good of posterity; very probably he carried this with him to the temple, whither he went on the third day of his illness, and hung it up in some proper place, that it might be read by all, and be sung by the priests and the Levites; and the Prophet Isaiah has thought fit to give it a place among his prophecies, that it might be transmitted to future ages: when he had been sick, and was recovered of his sickness; or, "on his being sick (e)"; on his sickness and recovery, which were the subject matter of his writing, as the following show; though it is true also of the time of writing it, which was after he had been ill, and was well again.

“bring again--cause to return (Jos 10:12-14). In Kg2 20:9, Kg2 20:11, 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, Jos 10:14). 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 (Kg2 16:7, Kg2 16:10). "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 Kg2 20:9, where translate, shall this shadow go forward, &c.; the dial was no doubt in sight, probably "in the middle court" (Kg2 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 (Kg2 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" (Ch2 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 (Dan 3:6).”
