Commentary for II Samuel 17:25
וְאֶת־עֲמָשָׂ֗א שָׂ֧ם אַבְשָׁלֹ֛ם תַּ֥חַת יוֹאָ֖ב עַל־הַצָּבָ֑א וַעֲמָשָׂ֣א בֶן־אִ֗ישׁ וּשְׁמוֹ֙ יִתְרָ֣א הַיִּשְׂרְאֵלִ֔י אֲשֶׁר־בָּא֙ אֶל־אֲבִיגַ֣ל בַּת־נָחָ֔שׁ אֲח֥וֹת צְרוּיָ֖ה אֵ֥ם יוֹאָֽב׃
And Absalom had set Amasa over the host instead of Joab. Now Amasa was the son of a man, whose name was Ithra the Jesraelite, that went in to Abigal the daughter of Nahash, sister to Zeruiah Joab’s mother.
Rashi on II Samuel
The daughter of Nochosh. This is Yeshai, Dovid's father. Our Rabbis said that [Yeshai] died without sin [but only] because of the serpent's counsel.8Baba Besra 16. The serpent in the Gan Fden who suggested to Chavah to eat from the Tree of knowledge. That sin brought death into the world. That is why Yeshai died because he had no sin of his own to merit death.
