Jesaja 37:21

The prophet's reply. "And Isaiah the son of Amoz sent to Hizkiyahu, saying, Thus saith Jehovah the God of Israel, That which thou hast prayed to me concerning Sennacherib the king of Asshur (K. adds, I have heard): this is the utterance which Jehovah utters concerning him." He sent, i.e., sent a message, viz., by one of his disciples (limmūdı̄m, Isa 8:16). According to the text of Isaiah, אשׁר would commence the protasis to הדּבר זה (as for that which - this is the utterance); or, as the Vav of the apodosis is wanting, it might introduce relative clauses to what precedes ("I, to whom:" Ges. 123, 1, Anm. 1). But both of these are very doubtful. We cannot dispense with שׁמעתּי (I have heard), which is given by both the lxx and Syr. in the text of Isaiah, as well as that of Kings. The prophecy of Isaiah which follows here, is in all respects one of the most magnificent that we meet with. It proceeds with strophe-like strides on the cothurnus of the Deborah style: "The virgin daughter of Zion despiseth thee, laugheth thee to scorn; the daughter of Jerusalem shaketh her head after thee. Whom hast thou reviled and blasphemed, and over whom hast thou spoken loftily, that thou hast lifted up thine eyes on high? Against the Holy One of Israel." The predicate is written at the head, in Isa 37:22, in the masculine, i.e., without any precise definition; since בּזה is a verb ל ה, and neither the participle nor the third pers. fem. of בּוּז. Zion is called a virgin, with reference to the shame with which it was threatened though without success (Isa 23:12); bethūlath bath are subordinate appositions, instead of co-ordinate. With a contented and heightened self-consciousness, she shakes her head behind him as he retreats with shame, saying by her attitude, as she moves her head back…

We may here observe, 1. That those who receive messages of terror from men with patience, and send messages of faith to God by prayer, may expect messages of grace and peace from God for their comfort, even when they are most cast down. Isaiah sent a long answer to Hezekiah's prayer in God's name, sent it in writing (for it was too long to be sent by word of mouth), and sent it by way of return to his prayer, relation being thereunto had: "Whereas thou hast prayed to me, know, for thy comfort, that thy prayer is heard." Isaiah might have referred him to the prophecies he had delivered (particularly that ch. 10) and bid him pick out an answer from thence; but, that he might have abundant consolation, a message is sent him on purpose. The correspondence between earth and heaven is never let fall on God's side. 2. Those who magnify themselves, especially who magnify themselves against God and his people, do really vilify themselves, and made themselves contemptible, in the eyes of all wise men: "The virgin, the daughter of Zion, has despised Sennacherib, and all his impotent malice and menaces; she knows that, while she preserves her integrity, she is sure of the divine protection, and that though the enemy may bark he cannot bite. All his threats are a jest; it is all but brutum fulmen - a mere flash," 3. Those who abuse the people of God affront God himself; and he takes what is said and done against them as said and done against himself: "Whom hast thou reproached? Even the Holy One of Israel, whom thou hast therefore reproached because he is a Holy One." And it aggravated the indignity Sennacherib did to God that he not only reproached him himself, but set his servants on to do the same: By thy servants, the abjects, thou hast reproached me. 4. Those who boast of thems…

37:21 Because you prayed: Prayer is powerful; it moved God’s heart and was part of the reason why the Lord answered with this message of hope.
