And it came to pass, when king Hezekiah heard it, that he rent his clothes, and covered himself with sackcloth, and went into the house of the LORD.

And when king Ezechias heard these words, he rent his garments, and covered himself with sackcloth, and went into the house of the Lord.

And it came to pass when king Hezekiah heard it, that he rent his garments, and covered himself with sackcloth, and went into the house of Jehovah.

And it cometh to pass, at king Hezekiah's hearing, that he rendeth his garments, and covereth himself with sackcloth, and entereth the house of Jehovah,

And on hearing it, King Hezekiah took off his robe, and put on haircloth, and went into the house of the Lord.

And when king Hezekiah had heard this, he tore his garments, and he covered himself with sackcloth, and he entered the house of the Lord.

Hezekiah, like his officers, probably rent his clothes on account of Rab-shakeh's blasphemies: and he put on sackcloth in self-humiliation and in grief. The only hope left was in Yahweh, for Egypt could not be trusted to effect anything of importance. Rab-shakeh's boldness had told upon Hezekiah. He was dispirited and dejected. He perhaps began to doubt whether he had done right in yielding to the bolder counsels of Eliakim and Isaiah. He had not lost his faith in God; but his faith was being severely tried. He wisely went and strove by prayer to strengthen it.

And it came to pass, when King Hezekiah heard it,.... The report of Rabshakeh's speech, recorded in the preceding chapter:
that he rent his clothes, and covered himself with sackcloth; rent his clothes because of the blasphemy in the speech; and he put on sackcloth, in token of mourning, for the calamities he feared were coming on him and his people: and he went into the house of the Lord; the temple, to pray unto him. The message he sent to Isaiah, with his answer, and the threatening letter of the king of Assyria, Hezekiah's prayer upon it, and the encouraging answer he had from the Lord, with the account of the destruction of the Assyrian army, and the death of Sennacherib, are the same "verbatim" as in Isaiah 37:1 throughout; and therefore the reader is referred thither for the exposition of them; only would add what Rauwolff (t) observes, that still to this day (1575) there are two great holes to be seen, wherein they flung the dead bodies (of the Assyrian army), one whereof is close by the road towards Bethlehem, the other towards the right hand against old Bethel.
(t) Travels, par. 3. ch. 22. p. 317.

Hezekiah discovered deep concern at the dishonour done to God by Rabshakeh's blasphemy. Those who speak from God to us, we should in a particular manner desire to speak to God for us. The great Prophet is the great Intercessor. Those are likely to prevail with God, who lift up their hearts in prayer. Man's extremity is God's opportunity. While his servants can speak nothing but terror to the profane, the proud, and the hypocritical, they have comfortable words for the discouraged believer.

HEZEKIAH IN DEEP AFFLICTION. (2-Kings 19:1-5)
when king Hezekiah heard it, he rent his clothes--The rending of his clothes was a mode of expressing horror at the daring blasphemy--the assumption of sackcloth a sign of his mental distress--his entrance into the temple to pray the refuge of a pious man in affliction--and the forwarding an account of the Assyrian's speech to Isaiah was to obtain the prophet's counsel and comfort. The expression in which the message was conveyed described, by a strong figure, the desperate condition of the kingdom, together with their own inability to help themselves; and it intimated also a hope, that the blasphemous defiance of Jehovah's power by the impious Assyrian might lead to some direct interposition for the vindication of His honor and supremacy to all heathen gods.

When Hezekiah had heard from his counsellors the report of Rabshakeh's words, he rent his clothes with horror at his daring mockery of the living God (2-Kings 19:4), put on mourning clothes as a sign of the trouble of his soul and went into the temple, and at the same time sent Eliakim and Shebna with the oldest of the priests in mourning costume to the prophet Isaiah, to entreat him to intercede with the Lord in these desperate circumstances.
(Note: "But the most wise king did not meet his blasphemies with weapons, but with prayer, and tears, and sackcloth, and entreated the prophet Isaiah to be his ambassador." - Theodoret.)
The order of the words: Isaiah the prophet, the son of Amoz, is unusual (cf. 2-Kings 14:25; 2-Kings 20:1; 1-Kings 16:7, etc.), and is therefore altered in Isaiah into Isaiah the son of Amoz, the prophet.

Rent his cloaths, &c. - Great men must not think it any disparagement to them, to sympathize with the injured honour of the great God.
