4 Kings (2 Kings) 19:1
Hezekiah discovered deep concern at the dishonour done to God by Rabshakeh's blasphemy. Those who speak from God to us, we should in a particular manner desire to speak to God for us. The great Prophet is the great Intercessor. Those are likely to prevail with God, who lift up their hearts in prayer. Man's extremity is God's opportunity. While his servants can speak nothing but terror to the profane, the proud, and the hypocritical, they have comfortable words for the discouraged believer.
4 Kings (2 Kings) 19:8
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.
4 Kings (2 Kings) 19:20
All Sennacherib's motions were under the Divine cognizance. God himself undertakes to defend the city; and that person, that place, cannot but be safe, which he undertakes to protect. The invasion of the Assyrians probably had prevented the land from being sown that year. The next is supposed to have been the sabbatical year, but the Lord engaged that the produce of the land should be sufficient for their support during those two years. As the performance of this promise was to be after the destruction of Sennacherib's army, it was a sign to Hezekiah's faith, assuring him of that present deliverance, as an earnest of the Lord's future care of the kingdom of Judah. This the Lord would perform, not for their righteousness, but his own glory. May our hearts be as good ground, that his word may strike root therein, and bring forth fruit in our lives.
4 Kings (2 Kings) 19:35
That night which followed the sending of this message to Hezekiah, the main body of their army was slain. See how weak the mightiest men are before Almighty God. Who ever hardened himself against Him and prospered? The king of Assyria's own sons became his murderers. Those whose children are undutiful, ought to consider whether they have not been so to their Father in heaven? This history exhibits a strong proof of the good of firm trust and confidence in God. He will afflict, but not forsake his people. It is well when our troubles drive us to our knees. But does it not reprove our unbelief? How unwilling are we to rest on the declaration of Jehovah! How desirous to know in what way he will save us! How impatient when relief is delayed! But we must wait for the fulfilling of his word. Lord, help our unbelief.
