29 Thus says the king: 'Do not let Hezeki'ah deceive you, for he will not be able to deliver you out of my hand. 30 Do not let Hezeki'ah make you to rely on the Lord by saying, The Lord will surely deliver us, and this city will not be given into the hand of the king of Assyria.' 31 Do not listen to Hezeki'ah; for thus says the king of Assyria: 'Make your peace with me and come out to me; then every one of you will eat of his own vine, and every one of his own fig tree, and every one of you will drink the water of his own cistern; 32 until I come and take you away to a land like your own land, a land of grain and wine, a land of bread and vineyards, a land of olive trees and honey, that you may live, and not die. And do not listen to Hezeki'ah when he misleads you by saying, The Lord will deliver us. 33 Has any of the gods of the nations ever delivered his land out of the hand of the king of Assyria? 34 Where are the gods of Hamath and Arpad? Where are the gods of Sepharva'im, Hena, and Ivvah? Have they delivered Sama'ria out of my hand? 35 Who among all the gods of the countries have delivered their countries out of my hand, that the Lord should deliver Jerusalem out of my hand?'" 36 But the people were silent and answered him not a word, for the king's command was, "Do not answer him."

(Read 2 Kings 18:17-37)
Rabshakeh tries to convince the Jews, that it was to no purpose for them to stand it out. What confidence is this wherein thou trustest? It were well if sinners would submit to the force of this argument, in seeking peace with God. It is, therefore, our wisdom to yield to him, because it is in vain to contend with him: what confidence is that which those trust in who stand out against him? A great deal of art there is in this speech of Rabshakeh; but a great deal of pride, malice, falsehood, and blasphemy. Hezekiah's nobles held their peace. There is a time to keep silence, as well as a time to speak; and there are those to whom to offer any thing religious or rational, is to cast pearls before swine. Their silence made Rabshakeh yet more proud and secure. It is often best to leave such persons to rail and blaspheme; a decided expression of abhorrence is the best testimony against them. The matter must be left to the Lord, who has all hearts in his hands, committing ourselves unto him in humble submission, believing hope, and fervent prayer.
