20 Do you think that mere words can substitute for military skill and strength? Who are you counting on, that you have rebelled against me? 21 On Egypt? If you lean on Egypt, it will be like a reed that splinters beneath your weight and pierces your hand. Pharaoh, the king of Egypt, is completely unreliable! 22 "But perhaps you will say to me, 'We are trusting in the Lord our God!' But isn't he the one who was insulted by Hezekiah? Didn't Hezekiah tear down his shrines and altars and make everyone in Judah and Jerusalem worship only at the altar here in Jerusalem? 23 "I'll tell you what! Strike a bargain with my master, the king of Assyria. I will give you 2,000 horses if you can find that many men to ride on them! 24 With your tiny army, how can you think of challenging even the weakest contingent of my master's troops, even with the help of Egypt's chariots and charioteers?

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.
