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.'

2 Kings 20:6 Meaning and Commentary

And I will add unto thy days fifteen years,....See Gill on "Isa 38:5"

and I will deliver thee, and this city, out of the hand of the king of Assyria; by which it appears that this sickness and recovery were before the destruction of the Assyrian army:

and I will defend this city for mine own sake, and for my servant David's sake: for the sake of his honour and glory in the temple, and the service of it, that were in Jerusalem, and for the sake of his promise to David and his seed.
