Matthew Henry on 2 Kings 19:1-7
The contents of Rabshakeh's speech being brought to Hezekiah, one would have expected (and it is likely Rabshakeh did expect) that he would call a council of war and it would be debated whether it was best to capitulate or no. Before the siege, he had taken counsel with his princes and his mighty men, Ch2 32:3. But that would not do now; his greatest relief is that he has a God to go to, and what passed between him and his God on this occasion we have here an account of.

Adam Clarke on 2 Kings 19:7

John Gill on 2 Kings 19:1
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…
