II Kings 19:1

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 (Kg2 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. Kg2 14:25; Kg2 20:1; Kg1 16:7, etc.), and is therefore altered in Isaiah into Isaiah the son of Amoz, the prophet.

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. I. Hezekiah discovered a deep concern at the dishonour done to God by Rabshakeh's blasphemy. When he heard it, though at second hand, he rent his clothes and covered himself with sackcloth, Kg2 19:1. Good men were wont to do so when they heard of any reproach cast on God's name; and great men must not think it any disparagement to them to sympathize with the injured honour of the great God. Royal robes are not too good to be rent, nor royal flesh too good to be clothed with sackcloth, in humiliation for indignities done to God and for the perils and terrors of his Jerusalem. To this God now called, and was displeased with those who were not thus affected. Isa 22:12-14, Behold joy and gladness, slaying oxen and killing sheep, though it was a day of trouble and perplexity in the valley of vision (Kg2 19:5), which refers to this very event. The king was in sackcloth, but many of his subjects were in soft clothing. II. He went up to the house of the Lord, according to the example of the psalmist, who, when he was grieved at the pride and prosperity of the wicked, went into the sanctuary of God and there understood their end, Psa 73:17. He went to the house of God, to meditate and pray, and get his spirit into a sedate composed frame, after this agitation. He was not considering what answer to return to Rabs…

19:1 Hezekiah showed his grief in the same way his representatives had (see Joel 1:13). He wisely went to the Temple, where he laid bare his soul before God in heartfelt worship and supplication (see Pss 5:7; 48:9-10; 63:1-3).
