21 Look, I know you are depending on Egypt, that splintered reed of a staff, which pierces the hand of anyone who leans on it! Such is Pharaoh king of Egypt to all who depend on him.
(Read 2 Kings 19:8-19)
Prayer is the never-failing resource of the tempted Christian, whether struggling with outward difficulties or inward foes. At the mercy-seat of his almighty Friend he opens his heart, spreads his case, like Hezekiah, and makes his appeal. When he can discern that the glory of God is engaged on his side, faith gains the victory, and he rejoices that he shall never be moved. The best pleas in prayer are taken from God's honour.
Matthew Henry's Commentary on 2 Kings 18:21
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.
