20 You say (but they are but vain words), ‘There is counsel and strength for war.’ Now on whom do you trust, that you have rebelled against me? 21 Now, behold, you trust in the staff of this bruised reed, even in Egypt. If a man leans on it, it will go into his hand, and pierce it. So is Pharaoh king of Egypt to all who trust on him. 22 But if you tell me, ‘We trust in Yahweh our God;’ isn’t that he whose high places and whose altars Hezekiah has taken away, and has said to Judah and to Jerusalem, ‘You shall worship before this altar in Jerusalem?’ 23 Now therefore, please give pledges to my master the king of Assyria, and I will give you two thousand horses, if you are able on your part to set riders on them. 24 How then can you turn away the face of one captain of the least of my master’s servants, and put your trust on Egypt for chariots and for horsemen?

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.
