The New John Gill Exposition of the Entire Bible2 Kings 20:10
And Hezekiah answered, it is a light thing for the shadow to
go down ten degrees…
That is, it was comparatively so, otherwise
to go down ten degrees at once would be extraordinary and miraculous;
but that was more agreeable to the nature and course of it to go
forward, and so the miracle would be less apparent:
nay, but let the shadow return backward ten degrees;
which was directly
contrary to its natural order and course, whereby the miracle would
appear more clear and manifest: these degrees are by some said F24 to
be half hours, and not full ones, since it is observed the sun shines
not twenty full hours on any dial, unless under the pole; the sun is
supposed to have been now at the fifth full hour; the sun was brought
back five whole hours, then came forward five, then came forward two
degrees, or one hour, to the sixth hour; which made sixteen; then it
was six hours to sunset; so that day was prolonged twenty two hours:
the Chinese F25 relate, that, in the time of Kingcungus, the planet
Mars, for sake of the king, went back three degrees.
