Isaiah 38:8

Behold, I will bring again the shadow of the degrees which is gone down in the sun-dial of Ahaz ten degrees backward. This dial seems to have been built up in semicircular form, in a series of steps, the size of which was such as to make them visible from the king's rooms. So the sun returned ten degrees, by which degrees it was gone down. The sun not only stood still, hut it actually moved backward for a short distance, by the command of the Lord. The sickness of Hezekiah was not the plague, but a fever with an eruption of ulcers or boils. The present account is much abbreviated, as a comparison with 2 Kings 20 shows, but all the essential points are included. One commentator here makes the remark: "How often our wishes, when gratified, prove curses! Hezekiah lived to have a son; that son was the idolater Manasseh, the chief cause of God's wrath against Judah and of the overthrow of the kingdom. "
