“Nakita mo ba kung paanong nagpakumbaba si Ahab sa harap Ko? Dahil nagpakumbaba siya sa harap Ko, hindi Ko ipararating ang kasamaan sa kanyang kapanahunan; sa kapanahunan ng kanyang anak ay ipararating Ko ang kasamaan sa kanyang sambahayan.”
From David to Destruction
After Eliyahu HaNavi delivers the curse against Achav and his descendants, Achav tears his clothing, dons sackcloth, and fasts (Melachim I 21:27). Hashem seems, as noted by Da’at Mikra, to revel and rejoice in Achav’s Teshuvah (Melachim I 21:29)! How are we to understand this surprising divine reaction? The question is especially poignant if one believes, as does the Malbim (as opposed to the Abarbanel), that Achav repents only due to fear of punishment, and not out of a desire to forge a proper connection with Hashem.
Ramban
HE WILL DESTROY THEM, AND HE WILL BRING THEM DOWN. The meaning thereof is that “He will bring them down and He will destroy them” [because, obviously, they could be destroyed after having been brought down, but not vice versa]. The expression ‘yachni’eim’ (He will bring them down) denotes “humiliation,” as in the usage, Seest thou how Ahab ‘nichna’ (humbleth himself) before Me?;110I Kings 21:29. if then perchance their uncircumcised heart ‘yikana’ (be humbled),111Leviticus 26:41. and so all [similar expressions]. And the purport thereof is that these peoples were very frightened of Israel. With a trembling heart,112Deuteronomy 28:65. low spirit and feebleness of hands113Jeremiah 47:3. they went out [against them in battle], as it is stated, And it came to pass, when all the kings of the Amorites, that were beyond the Jordan westward, and all the kings of the Canaanites, that were by the sea, heard how the Eternal had dried up the waters of the Jordan etc. that their heart melted, neither was there spirit in them any more, because of the children of Israel.114Joshua 5:1. It is possible that the expression He will destroy them alludes to the nations greater and mightier than thyself115Above, Verse 1. — and He will bring them down refers to the sons of the Anakim,116Verse 2. for despite all their might and height, their hearts were more humbled than [those of] the rest of the people and they did not go into battle at all, but were hiding in the mountains and in the fortified cities, as it is said, And Joshua came at that time, and cut off the Anakim from the hill-country, from Hebron, from Debir, from Anab, and from all the hill-country of Judah, and from all the hill-country of Israel; ‘with’ their cities Joshua utterly destroyed them,117Joshua 11:21. that is to say he destroyed them “in” their cities [indicating that the Anakim never entered the battlefield]. Similarly, it is said, And Judah went against the Canaanites that dwelt in Hebron etc. and they smote Sheshai, and Ahiman, and Talmai.118Judges 1:10. Here likewise it is stated that the Anakim were “in” Hebron, indicating that they were fearful of entering the field of battle.
Rabbeinu Bahya
We know the effect of humility on G’d from King Achav (Kings I 21,27-29) who humbled himself but once when admitting that he had sinned in allowing his wife to have Navot framed and executed. G’d used Achav’s repentance and humility to demonstrate to Elijah how much He valued such sentiments. He suspended the decree of death against him.
