Horns of iron - The horn in Scripture is the favorite symbol of power; and pushing with the horn is a common metaphor for attacking and conquering enemies (see Deuteronomy 33:17; Compare Psalm 44:5; Daniel 8:4). Zedekiah, in employing a symbolic action, was following the example of a former Israelite prophet 1 Kings 11:30.

Thus saith the Lord - Or, יהוה yehovâh. Zedekiah lays aside the unmeaningful "Lord" אדני 'ǎdonāy of the general company of Israelite prophets 1 Kings 22:6, and professes to have a direct message from Yahweh to Ahab. He may have believed his own words, for the "lying spirit" 1 Kings 22:22 may have seemed to him a messenger from Yahweh. All the rest followed his example 1 Kings 22:12.

Zedekiah - made him horns of iron - This was in imitation of that sort of prophecy which instructed by significative actions. This was frequent among the prophets of the Lord.

And Zedekiah the son of Chenaanah made him horns of iron,.... Horns are emblems of power and might, and iron ones of greater strength still; the prophets sometimes made use of visible signs, to represent the things they prophesied of should come to pass, see Isaiah 20:2, and the same method this prophet took:

and he saith, thus saith the Lord; imitating the true prophets: with these shall thou push the Syrians until thou hast consumed them: Abarbinel thinks he had in view the blessing of Joseph by Moses, Deuteronomy 33:17 where he is compared to a bullock with horns; and these said to be the ten thousands of Ephraim, and the thousands of Manasseh; and Ahab being of the tribe of Joseph, and ruling in Ephraim and Manasseh, the prophet chose to make use of this emblem for his encouragement.

And Zedekiah the son of Chenaanah made him {i} horns of iron: and he said, Thus saith the LORD, With these shalt thou push the Syrians, until thou have consumed them.

(i) The true prophets of God were accustomed to use signs for the confirmation of their doctrine, Isa 20:2, Jer 7:2 in which the false prophets imitated them, thinking by it to make their doctrine more believable.

11. Zedekiah the son of Chenaanah made him horns of iron-Small projections, of the size and form of our candle extinguishers (worn in many parts of the East as military ornaments), were worn by the Syrians of that time, and probably by the Israelite warriors also. Zedekiah, by assuming two horns, personated two heroes, and, pretending to be a prophet, wished in this manner to represent the kings of Israel and Judah in a military triumph. It was a symbolic action, to impart greater force to his language (see De 33:17); but it was little more than a flourish with a spontoon [Calmet, Fragments].

22:1-14 The same easiness of temper, which betrays some godly persons into friendship with the declared enemies of religion, renders it very dangerous to them. They will be drawn to wink at and countenance such conduct and conversation as they ought to protest against with abhorrence. Whithersoever a good man goes, he ought to take his religion with him, and not be ashamed to own it when he is with those who have no regard for it. Jehoshaphat had not left behind him, at Jerusalem, his affection and reverence for the word of the Lord, but avowed it, and endeavoured to bring it into Ahab's court. And Ahab's prophets, to please Jehoshaphat, made use of the name of Jehovah: to please Ahab, they said, Go up. But the false prophets cannot so mimic the true, but that he who has spiritual senses exercised, can discern the fallacy. One faithful prophet of the Lord was worth them all. Wordly men have in all ages been alike absurd in their views of religion. They would have the preacher fit his doctrine to the fashion of the times, and the taste of the hearers, and yet to add. Thus saith the Lord, to words that men would put into their mouths. They are ready to cry out against a man as rude and foolish, who scruples thus to try to secure his own interests, and to deceive others.
