וְהָיָה֙ הַנִּלְכָּ֣ד בַּחֵ֔רֶם יִשָּׂרֵ֣ף בָּאֵ֔שׁ אֹת֖וֹ וְאֶת־כָּל־אֲשֶׁר־ל֑וֹ כִּ֤י עָבַר֙ אֶת־בְּרִ֣ית יְהוָ֔ה וְכִֽי־עָשָׂ֥ה נְבָלָ֖ה בְּיִשְׂרָאֵֽל׃
"E será que aquele que for capturado no banimento será queimado pelo fogo, ele e tudo o que é seu, pois transgrediu a aliança de Hashem e cometeu uma vileza em Yisrael."
Sanhedrin
"for he committed an outrage in Israel."(Joshua 7:15) Rabbi Abba bar Zavda said, "This teaches that Achan had sex with an engaged woman. It says here "for he committed an outrage..."(Joshua 7:15) and it says over there, "for she committed an outrage in Israel."(Devarim 22:21).
