And I will add unto thy days fifteen years; and I will deliver thee and this city out of the hand of the king of Assyria; and I will defend this city for mine own sake, and for my servant David's sake.
Ver. 6. And I will add unto thy days fifteen years.] Thus God's grant to Hezekiah's prayer was not more speedy than bountiful. We are wont to reckon seven years for the life of a man, and now, behold, more than two lives hath God added to the age of Hezekiah. This also he did for him, notwithstanding those flaws in his prayer, those distrustful I said's, Isaiah 38:10,11 , &c. and albeit he foresaw that Hezekiah would "not render again according to the benefit done unto him." 2Ch 32:25
And I will deliver thee and this city.] Thus God is better to his people than their prayers; he doth for them "exceeding abundantly above all that they ask or think." Eph 3:20 Piscator here hence concludeth that Hezekiah began to be sick presently after the promise made of sending away the Assyrian out of the land. 2Ki 19:32
And for my servant David's sake,] i.e., For my promise's sake made to David. See on 2 Kings 20:5 .
