20 Do you think that mere words are any substitute for military strategy and troops? Now that you've revolted against me, who can you expect to help you? 21 You thought Egypt would, but Egypt's nothing but a paper tiger - one puff of wind and she collapses; Pharaoh king of Egypt is nothing but bluff and bluster. 22 Or are you going to tell me, 'We rely on God'? But Hezekiah has just eliminated most of the people's access to God by getting rid of all the local God-shrines, ordering everyone in Judah and Jerusalem, 'You must worship at the Jerusalem altar only.' 23 "So be reasonable. Make a deal with my master, the king of Assyria. I'll give you two thousand horses if you think you can provide riders for them. 24 You can't do it? Well, then, how do you think you're going to turn back even one raw buck private from my master's troops? How long are you going to hold on to that figment of your imagination, these hoped-for Egyptian chariots and horses?

Commentary on 2 Kings 18:17-37
(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.
