Coke's Commentary on the Holy Bible
Isaiah 39:8
Then said Hezekiah to Isaiah— Hezekiah, convinced of his error, and perceiving that he had justly provoked the divine indignation, acknowledges his fault, and humbles himself greatly for his pride, as is recorded to his praise, 2 Chronicles 32:26. And these words afford us a strong proof of his humility; wherein he acknowledges the divine justice, and at the same time extols the great lenity and goodness of God, in sparing him, and delaying for a season that punishment which he might so justly have inflicted upon him. Calmet and others would render and understand the passage thus: "What thou hast told me from the Lord is good: I willingly submit to it; but shall peace and truth continue in my time? May I flatter myself with the hope of so much indulgence and mercy?"
REFLECTIONS.—1st, Though nothing could appear more promising than Hezekiah's late professions, and in general he did approve himself faithful, yet in some things he failed, as in the history here recorded, where his pride and vanity reduced him; so that, as it is observed by the sacred historian, 2 Chronicles 32:25, He rendered not again according to the benefit done unto him.
This history we have had before, 2 Kings 20:12; Exodus 20:21 and may just add to what has been already observed, [1.] How hard it is to be kept humble under distinguished mercies and this world's wealth. [2.] They will be courted in prosperity, who in adversity would be despised. [3.] When it becomes their interest, the enemies of religion will caress God's people; but their kisses are commonly deceitful. [4.] An affectation of displaying our improvements, wealth, buildings, &c. to strangers, and taking a secret pleasure in doing so, evinces the vanity of the heart, and often that most, when we affect to call them trifles. [5.] God will not see his children puffed up, without sending them the needful rebuke: it is well if, like Hezekiah, we take shame to ourselves, and confess our folly.
2nd, It was a mortifying message which the prophet brought him; but it was a blessed symptom of Hezekiah's gracious spirit, that so humbly he acquiesced in the divine judgment. It may teach us, [1.] That it is just in God to take from us the gifts that we abuse. [2.] Not to be desirous of, or value ourselves upon, the respect paid us by the children of this world: our intimacy and connections with them usually in their issue prove our plague. [3.] True prophets of God must not spare the faithful reproof; and true penitents will, so far from being offended, receive it with thankfulness. [4.] When God is pleased to resume his gifts which we have abused, or to punish us by afflictions in world for our sins, it becomes us to bear the rod with quietness, and justify him in his judgments. While we are out of hell, all our sufferings are infinitely less than we deserve. [5.] Though we cannot but be concerned about the evils which we foresee, yet every moment's respite is a mercy to be acknowledged.
