And it came to pass that night, that the angel of the LORD went out, and smote in the camp of the Assyrians an hundred fourscore and five thousand: and when they arose early in the morning, behold, they were all dead corpses.

Wesley's Notes

Jamieson-Fausset-Brown Bible Commentary

2Ki 19:35, 36. An Angel Destroys the Assyrians.

35. in the morning . they were all dead corpses-It was the miraculous interposition of the Almighty that defended Jerusalem. As to the secondary agent employed in the destruction of the Assyrian army, it is most probable that it was effected by a hot south wind, the simoon, such as to this day often envelops and destroys whole caravans. This conjecture is supported by 2Ki 19:7 and Jer 51:1. The destruction was during the night; the officers and soldiers, being in full security, were negligent; their discipline was relaxed; the camp guards were not alert, or perhaps they themselves were the first taken off, and those who slept, not wrapped up, imbibed the poison plentifully. If this had been an evening of dissolute mirth (no uncommon thing in a camp), their joy (perhaps for a victory), or "the first night of their attacking the city," says Josephus, became, by its effects, one means of their destruction [Calmet, Fragments].

Matthew Henry's Concise Commentary

19:35-37 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.

Matthew Henry's Whole Bible Commentary

Verses 35-37

Sometimes it was long ere prophecies were accomplished and promises performed; but here the word was no sooner spoken than the work was done.

I. The army of Assyria was entirely routed. That night which immediately followed the sending of this message to Hezekiah, when the enemy had just set down before the city and were preparing (as we now say) to open the trenches, that night was the main body of their army slain upon the spot by an angel, v. 35. Hezekiah had not force sufficient to sally out upon them and attack their camp, nor would God do it by sword or bow; but he sent his angel, a destroying angel, in the dead of the night, to make an assault upon them, which their sentinels, though ever so wakeful, could neither discover nor resist. It was not by the sword of a mighty man or of a mean man, that is, not of any man at all, but of an angel, that the Assyrians army was to fall (Isa. 31:8), such an angel as slew the first-born of Egypt. Josephus says it was done by a pestilential disease, which was instant death to them. The number slain was very great, 185,000 men, and Rabshakeh, it is likely, among the rest. When the besieged arose, early in the morning, behold they were all dead corpses, scarcely a living man among them. Some think the 76th Psalm was penned on this occasion, where we read that the stout-hearted were spoiled and slept their sleep, their last, their long sleep, v. 5. See how great, in power and might, the holy angels are, when one angel, in one night, could make so great a slaughter. See how weak the mightiest of men are before almighty God: who ever hardened himself against him and prospered? The pride and blasphemy of the king are punished by the destruction of his army. All these lives are sacrificed to God's glory and Zion's safety. The prophet shows that therefore God suffered this vast rendezvous to be made, that they might be gathered as sheaves into the floor, Mic. 4:12, 13.

II. The king of Assyria was hereby put into the utmost confusion. Ashamed to see himself, after all his proud boasts, thus defeated and disabled to pursue his conquests and secure what he had (for this, we may suppose, was the flower of his army), and continually afraid of falling under the like stroke himself, He departed, and went, and returned; the manner of the expression intimates the great disorder and distraction of mind he was in, v. 36. And it was not long before God cut him off too, by the hands of two of his own sons, v. 37. 1. Those that did it were very wicked, to kill their own father (whom they were bound to protect) and in the act of his devotion; monstrous villany! But, 2. God was righteous in it. Justly are the sons suffered to rebel against their father that begat them, when he was in rebellion against the God that made him. Those whose children are undutiful to them ought to consider whether they have not been so to their Father in heaven. The God of Israel had done enough to convince him that he was the only true God, whom therefore he ought to worship; yet he persists in his idolatry, and seeks to his false god for protection against a God of irresistible power. Justly is his blood mingled with his sacrifices, since he will not be convinced by such a plain and dear-bought demonstration of his folly in worshipping idols. His sons that murdered him were suffered to escape, and no pursuit was made after them, his subjects perhaps being weary of the government of so proud a man and thinking themselves well rid of him. And his sons would be looked upon as the more excusable in what they had done if it be true (as bishop Patrick suggested) that he was now vowing to sacrifice them to his god, so that it was for their own preservation that they sacrificed him. His successor was another son, Esarhaddon, who (as it should seem) did not aim, like his father, to enlarge his conquests, but rather to improve them; for he it was that first sent colonies of Assyrians to inhabit the country of Samaria, though it is mentioned before (ch. 17:24), as appears, Ezra 4:2, where the Samaritans say it was Esarhaddon that brought them thither.

CHAPER 20

In this chapter we have, I. Hezekiah's sickness, and his recovery from that, in answer to prayer, in performance of a promise, in the use of means, and confirmed with a sign (v. 1-11). II. Hezekiah's sin, and his recovery from that (v. 12-19). In both of these, Isaiah was God's messenger to him. III. The conclusion of his reign (v. 20, 21).
