Melachim Alef 22:11 Meaning and Commentary

1 Kings 22:11

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 Isaiah 20:3 ) ( Jeremiah 27:2 ) , 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.

Melachim Alef 22:11 In-Context

9 Then HaMelech Yisroel called an officer, and said, Hasten here Mikhay’hu ben Yimlah.

10 And the Melech Yisroel and Yehoshaphat Melech Yehudah sat each on his kisse, having put on their robes, at the threshing floor in the entrance of sha’ar Shomron; all the nevi’im prophesied before them.

11 Tzidkiyah ben Kenaanah made him [goring] horns of barzel: and said, Thus saith Hashem, With these shalt thou push Aram until thou have consumed them.

12 And all the nevi’im prophesied so, saying, Go up to Ramot-Gil‘ad, and succeed: for Hashem shall deliver it into the yad HaMelech.

13 And the malach that was gone to summon Mikhay’hu spoke unto him, saying, Hinei now, the words of the nevi’im declare tov unto HaMelech with one mouth: let thy word be like the word of one of them, speak that which is tov.
