2 Kings 20:8 YLT

⁶  and I have added to thy days fifteen years, and out of the hand of the king of Asshur I deliver thee and this city, and have covered over this city for Mine own sake, and for the sake of David My servant.'

⁷  And Isaiah saith, 'Take ye a cake of figs;' and they take and lay 'it' on the boil, and he reviveth.

⁸  And Hezekiah saith unto Isaiah, 'What 'is' the sign that Jehovah doth give healing to me, that I have gone up on the third day to the house of Jehovah?'

⁹  And Isaiah saith, 'This 'is' to thee the sign from Jehovah, that Jehovah doth the thing that He hath spoken -- The shadow hath gone on ten degrees, or it doth turn back ten degrees?'

¹⁰  And Hezekiah saith, 'It hath been light for the shadow to incline ten degrees: nay, but let the shadow turn backward ten degrees.'
