Isaiah 39:3

(Verse 3) Then Isaiah the Prophet came to King Hezekiah and said to him: What did these men say, and where did they come from to you? And Hezekiah said: They have come to me from a distant land, from Babylon. The Hebrews report that Hezekiah fell ill for this reason: because after the unheard of victory of the Jews and the death of the Assyrian king, he did not sing praises to the Lord, which Moses sang after the drowning of Pharaoh (Exod. XV), and Deborah after the killing of Sisera (Judges IV), and Anna after the birth of Samuel (1 Samuel II). Hence, he was reminded of his weakness. And again, after regaining his health and the greatness of the sign, he offered another opportunity for pride, which as a wise man and worshiper of God, he should have avoided; not showing his wealth to foreigners, which he possessed by the grace of God. From which, according to the Laws of tropology, we learn that we should not throw pearls before swine, nor give what is holy to dogs (Matth. VII). For whoever has a faithful spirit conceals his affairs; and whoever does not do this, all his power is weakened; and his posterity perishes, and with the loss of manly strength, he is reduced to feminine softness (Prov. XI, 13-15). Therefore, Isaiah enters the king's presence and inquires as if unaware. What did these men say, and where did they come from? Two questions, what they said and where they came from, were asked. He responded to one, ignoring the other: this must be read with emphasis and a raised eyebrow: They came from a distant land, from Babylon: the longer the distance from where they came, the more glorious they are because of whom they came to see. And he said, they came to me; he should have said, they came to glorify God for the greatness of the sign, from Babylon, which is the most powerful city in the whole world.

When the ambassadors of the Babylonian king came to Hezekiah, his heart in a fresh access of human weakness was lifted up with pride, and he received them with all gladness, for his own glory; and contrary to the will of God, he led them into the palace, displaying to them his treasures and all his riches. Then again Isaiah was sent to him to correct his frame of mind, and said to him ironically: What do these men say, and whence came they unto thee? And Hezekiah said: From a far country have they come unto me—even from Babylon. Then said Isaiah again: What have they seen in thine house? But the King, seeing that the Prophet put the question knowing how matters stood, told the truth and said to him: All that is in my house have they seen, and there is nothing in the house which they have not seen—yea they have even seen all my treasures: Then he told him, by way of a threat to chastise the pride which uplifted his heart, what would come to pass after him and says: Hear the word of the Lord of Hosts. Behold the days come, that all that is in thine house, and that which thy fathers have laid up in store until this day, shall be carried to Babylon: nothing shall be left, saith the Lord. And of thy sons that shall issue from thee, which thou shalt beget, shall they take away, and they shall be eunuchs in the palace of the King of Babylon; as if He said, For you ought to have been instructed by your former experiences that, not so much for your glory as for Mine, were the mighty signs wrought, in order that the nations also may be made acquainted with My greatness, which thou again didst think lightly of, and wert uplifted with pride, not giving Me thanks. But since without My sanction thou didst receive the ambassadors, and didst show them the wealth which thou hast obtained from Me, be therefore henceforth taught that hereafter, in the time of thy successors, I will deliver over to the Babylonians all thy wealth to be plundered and captured, because thou hadst again no regard for My glory, but didst honour thyself in preference to Me. But inasmuch as thou hast ever been virtuous and pious, none of these things shall happen in thy times. Hezekiah, on hearing and understanding this, humbled himself, as he was a righteous man and obedient to God, and giving thanks said to Isaiah: Good is the word of the Lord which he hath spoken. Let there be peace in my days

Third, he sets out the reprimand of his vainglory: then Isaiah the prophet came.

And first, he sets out the inquiry and the manifestation of his fault: there was not any thing which I have not shown them in my treasures: counsel in the heart of a man is like deep water (Prov 20:5).
