Howbeit in the business of the ambassadors of the princes of Babylon, who sent unto him to enquire of the wonder that was done in the land, God left him, to {u} try him, that he might know all that was in his heart.

(u) Here we see the reason why the faithful are tempted, which is to determine whether they have faith or not, and that they may feel the presence of God who does not allow them to be overcome by temptations, but in their weakness administers strength.

Wesley's Notes

32:31 Wonder that was done - Either the destruction of the Assyrians, or the going back of the sun. These miracles were wrought to alarm and awaken a stupid, careless world, and to turn them from dumb and lame idols to the living God. God left him - To himself, and suffered Satan to try him; that he might know he had infirmities and sins as well as virtues. O what need have great men, and good men, and useful men, to study their own follies and infirmities, and to beg earnestly of God, that he would hide pride from them!

Jamieson-Fausset-Brown Bible Commentary

31. in the business of the ambassadors who sent . to inquire of the wonder that was done in the land, &c.-They brought a present (2Ch 32:23; see on [470]2Ki 20:12, 13), and a letter of congratulation on his recovery, in which particular enquiries were made about the miracle of the sun's retrocession-a natural phenomenon that could not fail to excite great interest and curiosity at Babylon, where astronomy was so much studied. At the same time, there is reason to believe that they proposed a defensive league against the Assyrians.

God left him, to try him, &c.-Hezekiah's offense was not so much in the display of his military stores and treasures, as in not giving to God the glory both of the miracle and of his recovery, and thus leading those heathen ambassadors to know Him.

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.
