The Daily Ma’amar by our Rebbe Rav Eliezer Berland shlit”a, courtesy of the “Hashem Hu HaElokim” leaflet:
Achav came to the world to rectify the “Goren HaAtad [Bramble Barn]” and so therefore it is said about Achav, “He walked about slowly (at) (I Melachim 21:27), and the letter dalet is rectified through the Alef-Alef-Bet letters of “Ahav,” in the mystery of “The foundations 510 of the earth 432 were laid bare 49” = 991, the secret of Mashiach 358 ben 52 Yosef 156 Meshicha 359 ben 52 David 14 = 991, and so Hashem rained down on Sodom and Amora fire 301 and sulfur 699 = 1000, the numerical value of Mashiach 358 ben 52 Yosef 156 Mashiach 358 ben 52 David [with a yud] 24 = 1000.
Because Achav had needed to rectify the world of the feminine, which is Rachel, the secret of the Land of Israel. And he blemished in exactly the opposite fashion, and erected on every single furrow an idolatrous image, from Beer Sheva to Dan.
For the Ramchal explains, that Achav came from Ephraim, and was supposed to be Mashiach ben Yosef, because furrow (telem) plus David = 484 = vav (ויו) x vav [22 x 22]. And if Achav had nullified himself to Yehoshafat who came from the House of David, he himself would have merited to be Mashiach ben Yosef and Yehoshafat ben Asa would have been Mashiach ben David, and in every single furrow, instead of building an image to idolatry, he would have announced that “Hashem is God, Hashem is God,” and then he would have fulfilled in Aram: “I pulverized them 455 like the dust 370 of the earth 291” = 1116, and Achav would have merited to be the “father 13 of orphans 506 and the defender 70 of widows 527” = 1116, and to be Mashiach ben Yosef.
“Like mud 38 of the streets 510, I poured them out 351” plus 11 = 910 chieftains of Esav, the numerical value of “Do not 31 fear 611 My servant 86 Yaakov 182” = 910.
