2 Kings 1:5

the messengers turned back--They did not know the stranger; but his authoritative tone, commanding attitude, and affecting message determined them at once to return.

We have here Ahaziah, the wicked king of Israel, under God's rebukes both by his providence and by his prophet, by his rod and by his word.
I. He is crossed in his affairs. How can those expect to prosper that do evil in the sight of the Lord, and provoke him to anger? When he rebelled against God, and revolted from his allegiance to him, Moab rebelled against Israel, and revolted from the subjection that had long paid to the kings of Israel, Kg2 1:1. The Edomites that bordered on Judah, and were tributaries to the kings of Judah, still continued so, as we find in the chapter before (v. 47), till, in the wicked reign of Joram, they broke that yoke (Kg2 8:22) as the Moabites did now. If men break their covenants with us, and neglect their duty, we must reflect upon our breach of covenant with God, and the neglect of our duty to him. Sin weakens and impoverishes us. We shall hear of the Moabites, Kg2 3:5.
II. He is seized with sickness in body, not from any inward cause, but by a severe accident. He fell down through a lattice, and was much bruised with the fall; perhaps it threw him into a fever, Kg2 3:2. Whatever we go, there is but a step between us and death. A man's house is his castle, but not to secure him against the judgments of God. The cracked lattice is a fatal to the son, when God pleases to make it so, as the bow drawn at a venture was to the father. Ahaziah would not attempt to reduce the Moabites, lest he should perish in the field of battle: but he is not safe, though he tarry at home. Royal palaces do not always yield firm footing. The snare is laid for the sinner in the ground where he thinks least of it, Job 18:9, Job 18:10. The whole creation, which groans under the man's sin, will at length sink and break under the weight, like this lattice. He is never safe that has God for his enemy.
III. In his distress he sends messengers to enquire of the god Ekron whether he should recover or no, Kg2 1:2. And here, 1. His enquiry was very foolish: Shall I recover? Even nature itself would rather have asked, "What means may I use that I may recover?" But as one solicitous only to know his fortune, not to know his duty, his question is only this, Shall I recover? to which a little time would give an answer. We should be more thoughtful what will become of us after death than how, or when, or where, we shall die, and more desirous to be told how we may conduct ourselves well in our sickness, and get good to our souls by it, than whether we shall recover from it. 2. His sending to Baal-zebub was very wicked; to make a dead and dumb idol, perhaps newly erected (for idolaters were fond of new gods), his oracle, was not less a reproach to his reason than to his religion. Baal-zebub, which signifies the lord of a fly, was one of their Baals that perhaps gave his answers either by the power of the demons or the craft of the priests, with a humming noise, like that of a great fly, or that had (as they fancied) rid their country of the swarms of flies wherewith it was infested, or of some pestilential disease brought among them by flies. Perhaps this dunghill-deity was as famous then as the oracle of Delphos was, long afterwards, in Greece. In the New Testament the prince of the devils is called Beel-zebub (Mat 12:24), for the gods of the Gentiles were devils, and this perhaps grew to be one of the most famous.
IV. Elijah, by direction from God, meets the messengers, and turns them back with an answer that shall save them the labour of going to Ekron. Had Ahaziah sent for Elijah, humbled himself, and begged his prayers, he might have had an answer of peace; but if he send to the god of Ekron, instead of the God of Israel, this, like Saul's consulting the witch, shall fill the measure of his iniquity, and bring upon him a sentence of death. Those that will not enquire of the word of God for their comfort shall be made to hear it, whether they will or not, to their amazement.
1. He faithfully reproves his sin (Kg2 1:3): Is it not because there is not (that is, because you think there is not) a God in Israel (because there is no God, none in Israel, so it may be read), that you go to enquire of Baal-zebub, the god of Ekron, a despicable town of the Philistines (Zac 9:7), long since vanquished by Israel? Here, (1.) The sin was bad enough, giving that honour to the devil which is due to God alone, which was done as much by their enquiries as by their sacrifices. Note, It is a very wicked thing, upon any occasion or pretence whatsoever, to consult with the devil. This wickedness reigned in the heathen world (Isa 47:12, Isa 47:13) and remains too much even in the Christian world, and the devil's kingdom is supported by it. (2.) The construction which Elijah, in God's name, puts upon it, makes it much worse: "It is because you think not only that the God of Israel is not able to tell you, but that there is no God at all in Israel, else you would not send so far for a divine answer." Note, A practical and constructive atheism is the cause and malignity of our departures from God. Surely we think there is no God in Israel when we live at large, make flesh our arm, and seek a portion in the things of this world.
2. He plainly reads his doom: Go, tell him he shall surely die, Kg2 1:4. "Since he is so anxious to know his fate, this is it; let him make the best of it." The certain fearful looking for of judgment and indignation which this message must needs cause cannot but cut him to the heart.
V. The message being delivered to him by his servants, he enquires of them by whom it was sent to him, and concludes, by their description of him, that it must be Elijah, Kg2 1:7, Kg2 1:8. For, 1. His dress was the same that he had seen him in, in his father's court. He was clad in a hairy garment, and had a leathern girdle about him, was plain and homely in his garb. John Baptist, the Elias of the New Testament, herein resembled him, for his clothes were made of hair cloth, and he was girt with a leathern girdle, Mat 3:4. He that was clothed with the Spirit despised all rich and gay clothing. 2. His message was such as he used to deliver to his father, to whom he never prophesied good, but evil. Elijah is one of those witnesses that still torment the inhabitants of the earth, Rev 11:10. He that was a thorn in Ahab's eyes will be so in the eyes of his son while he treads in the steps of his father's wickedness; and he is ready to cry out, as his father did, Hast thou found me, O my enemy? Let sinners consider that the word which took hold of their fathers is still as quick and powerful as ever. See Zac 1:6; Heb 4:12.

But shalt surely die - The true God tells you this; he in whose hands are both life and death, who can kill and make alive. Baal-zebub can do nothing; God has determined that your master shall die.

And when the messengers turned back unto him,.... To Ahaziah king of Israel, as they did as soon as Elijah was gone from them; concluding from his habit, his gravity, and the authority with which he spoke, that he was a prophet of the Lord, and especially from his knowledge of them, and of what they were sent about:

he said unto them, why are ye now turned back? for, by the time they had been gone, he knew they could never have been at Ekron and returned.

Before you have been at Ekron; which he easily knew by their quick return.

After the death of Ahab, Moab rebelled against Israel (Kg2 1:1). The Moabites, who had been subjugated by David (Sa2 8:2), had remained tributary to the kingdom of the ten tribes after the division of the kingdom. but when Israel was defeated by the Syrians at Ramoth in the time of Ahab, they took advantage of this defeat and the weakening of the Israelitish power in the country to the east of the Jordan to shake off the yoke of the Israelites, and very soon afterwards attempted an invasion of the kingdom of Judah, in alliance with the Edomite and other tribes of the desert, which terminated, however, in a great defeat, though it contributed to the maintenance of their independence. For further remarks, see at Kg2 3:4.
Kg2 1:2
Ahaziah could not do anything to subjugate the Moabites any further, since he was very soon afterwards taken grievously ill. He fell through the grating in his upper room at Samaria. השּׂבכה, the grating, is either a window furnished with a shutter of lattice-work, or a door of lattice-work in the upper room of the palace, but hardly a grating in the floor of the Aliyah for the purpose of letting light into the lower rooms, as the Rabbins supposed. On account of this misfortune, Ahaziah resorted to the Ekronitish Baalzebub to obtain an oracle concerning the result of his illness. בּעל־זבוּב, i.e., Fly-Baal, was not merely the "averter of swarms of insects," like the Ζεὺς ἀπομυῖος, μυίαγρος of Elis (Ges., Winer, Movers, Phniz. i. p. 175), since "the Fly-God cannot have received his name as the enemy of flies, like lucus a non lucendo," but was Μυῖα θεός (lxx, Joseph.), i.e., God represented as a fly, as a fly-idol, to which the name Myiodes, gnat-like, in Plin. h. n. xxix. 6, clearly points, and as a god of the sun and of summer must have stood in a similar relation to the flies to that of the oracle-god Apollo, who both sent diseases and took them away (vid., J. G. Mller, Art. Beelzebub in Herzog's Cycl. i. p. 768, and Stark, Gaza, pp. 260,261). The latter observes that "these (the flies), which are governed in their coming and going by all the conditions of the weather, are apparently endowed with prophetic power themselves." This explains the fact that a special power of prophecy was attributed to this god.
(Note: The later Jews altered the name Beelzebub into Βεελζεβούλ, i.e., probably lord of the (heavenly) dwelling, as a name given to the ἄρχων τῶν δαιμονίων (Mat 10:25, etc.); and the later Rabbins finally, by changing זבוּל בּעל into זבל בּעל, made a fly-god into a dung-god, to express in the most intense form their abomination of idolatry (see Lightfoot, Horae hebr. et talm. in Mat 12:24, and my Bibl. Archol. i. pp. 440,441).)
Ekron, now Akir, the most northerly of the five Philistine capitals (see at Jos 13:3).
Kg2 1:3-4
But the angel of the Lord, the mediator of the revelations made by the invisible God to the covenant nation (see Comm. on the Pentateuch, vol. i. pp. 185-191, transl.), had spoken to Elijah to go and meet the king's messengers, who were going to inquire of Baalzebub, and to ask them whether it was from the want of a God in Israel (אין מבּלי as in Exo 14:11; see Ewald, 323, a.) that they turned to Baalzebub, and to announce to them the word of Jehovah, that Ahaziah would not rise up from his bed again, but would die. "And Elijah went," sc. to carry out the divine commission.
Kg2 1:5-8
The messengers did not recognise Elijah, but yet they turned back and reported the occurrence to the king, who knew at once, from the description they gave of the habitus of the man in reply to his question, that it was Elijah the Tishbite. האישׁ משׁפּט מה: "what was the manner of the man?" משׁפּט is used here to denote the peculiarity of a person, that which in a certain sense constitutes the vital law and right of the individual personality; figura et habitus (Vulg.). The servants described the prophet according to his outward appearance, which in a man of character is a reflection of his inner man, as שׂער בּעל אישׁ, vir pilosus, hirsutus. This does not mean a man with a luxuriant growth of hair, but refers to the hairy dress, i.e., the garment made of sheep-skin or goat-skin or coarse camel-hair, which was wrapped round his body; the אדּרת (Kg2 2:8; Kg1 19:13), or שׂער אדּרת (Zac 13:4, cf. Mat 3:4; Heb 11:37), which was worn by the prophets, not as mere ascetics, but as preachers of repentance, the rough garment denoting the severity of the divine judgments upon the effeminate nation, which revelled in luxuriance and worldly lust. And this was also in keeping with "the leather girdle," עור אזור, ζώνη δερματίνη (Mat 3:4), whereas the ordinary girdle was of cotton or linen, and often very costly.
