But Hezekiah rendered not again according to the benefit done unto him; for his heart {s} was lifted up: therefore there was wrath upon him, and upon Judah and Jerusalem.

(s) He was lifted up with the pride of his victory and treasures, and shows them for an ostentation to the ambassadors of Babylon.

Wesley's Notes

32:25 Lifted up - For that prodigious victory over the Assyrians, for his miraculous restoration from sickness, and for the honour since done him by an embassy from the great king of Babylon. All which probably raised in him too great an opinion of himself, as if these things were done for his piety and virtues.

Matthew Henry's Concise Commentary

32:24-33 God left Hezekiah to himself, that, by this trial and his weakness in it, what was in his heart might be known; that he was not so perfect in grace as he thought he was. It is good for us to know ourselves, and our own weakness and sinfulness, that we may not be conceited, or self-confident, but may always live in dependence upon Divine grace. We know not the corruption of our own hearts, nor what we shall do if God leaves us to ourselves. His sin was, that his heart was lifted up. What need have great men, and good men, and useful men, to study their own infirmities and follies, and their obligations to free grace, that they may never think highly of themselves; but beg earnestly of God, that he will always keep them humble! Hezekiah made a bad return to God for his favours, by making even those favours the food and fuel of his pride. Let us shun the occasions of sin: let us avoid the company, the amusements, the books, yea, the very sights that may administer to sin. Let us commit ourselves continually to God's care and protection; and beg of him never to leave us nor forsake us. Blessed be God, death will soon end the believer's conflict; then pride and every sin will be abolished. He will no more be tempted to withhold the praise which belongs to the God of his salvation.
