Commentaire sur Rois 2 12:22

Yozochor the son of Shimos, and Yehozovod the son of Shomeir. In Divrei Hayomim it is written, “[Zovod, son of] Shimos the Amonite and Yehozovod, son of Shimris the Moavite.”¹⁷II Divrei Hayomim 24:26. These men are listed as the ones who rebelled against Yehoash. Why did Scripture specify? To teach us that the Holy One, Blessed Is He, requited him through people with traits similar to his. Let the ungrateful Amonites and Moavites, who ignored our father Avrohom’s favor, which he did for Lot, (that he fought with the kings to rescue him, yet they hired Bilaam to curse his descendants), and he will requite Yoash who ignored the favor of Yehoyoda, and killed Zecharyohu his son, as it is explained [in Scripture].¹⁸Ibid. v. 21-22. This Midrash is in Sifrei.
