Divrey Hayamim Bais 25:3-5

Orthodox Jewish Bible

³ Now it came to pass, when the mamlachah was established under him, that he slaughtered his avadim that had murdered HaMelech Aviv.

⁴ But he slaughtered not their banim, but did as it is written in the Torah in the Sefer Moshe, where Hashem commanded, saying, The avot shall not die for the banim, neither shall the banim die for the avot, but every ish shall die for his own chet.

⁵ Moreover Amatzyahu gathered Yehudah together, and set them in order in Bais Avot by officers of thousands and officers of hundreds, throughout all Yehudah and Binyamin; and he mustered them from esrim shanah and above, and found them three hundred elef bachur, battleready choice men, that could handle spear and shield.
