Answer him not - The blasphemy is too barefaced; Jehovah is insulted, not you; let him avenge his own quarrel. See the succeeding chapter, 2 Kings 19 (note).

The people were quite silent at this address ("the people," העם, to whom Rabshakeh had wished to address himself); for Hezekiah had forbidden them to make any answer, not only to prevent Rabshakeh from saying anything further, but that the ambassadors of Sennacherib might be left in complete uncertainty as to the impression made by their words. The deputies of Hezekiah returned to the king with their clothes rent as a sign of grief at the words of the Assyrian, by which not only Hezekiah, but still more Jehovah, had been blasphemed, and reported what they had heard.

But the people held their peace, and answered him not a word: for the king's commandment was, saying, Answer him not.

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.
