There are sons who were disgraced through their fathers. This is Josiah, who was disgraced through Amon, as it is said, "For he, Amon, multiplied guilt" (II Chronicles 33:23). Hezekiah was disgraced through Ahaz, as it is said, "bind up the testimony" (Isaiah 8:16). And there are fathers who were disgraced through their sons. Eli was disgraced through his sons, as it is said, "And the sons of Eli were sons of Belial" (I Samuel 2:12). Samuel was disgraced through his sons, as it is said, "And his sons did not walk in his ways" (I Samuel 8:3). But Abraham was made great through Isaac, and Isaac was made great through him. As it is said, "And the two of them walked together" (Genesis 22:6), and it is written, "Abraham begot Isaac" (Genesis 25:19). Now did he beget only Isaac? Rather, that he was made great through him.
Abraham and Isaac Each Honored Through the Other
Yalkut Shimoni on Torah 110:11
יֵשׁ בָּנִים שְׁנִתְגָּנוּ בַּאֲבִיהֶם זֶה יֹאשִׁיָּהוּ שֶׁנִתְגַּנָה בְּאָמוֹן (דה"ב לג, כג), "כִּי הוּא אָמוֹן הִרְבָּה אַשְׁמָה". חִזְקִיָּה נִתְגַּנָה בֶּאָחָז שֶׁנֶּאֱמַר "צוֹר תְּעוּדָה וְיֵשׁ אָבוֹת שְׁנִתְגָּנוּ בִּבְנֵיהֶם, עֵלִי נִתְגַּנָה בְּבָנָיו (שמואל א ב, יג), "וּבְנֵי עֵלִי בְּנֵי בְּלִיָּעַל". שְׁמוּאֵל נִתְגַּנָה בְּבָנָיו (שם ח, ג), "וְלֹא הָלְכוּ בָנָיו בִּדְרָכָיו". אֲבָל אַבְרָהָם הוּא נִתְגַּדֵּל בְּיִצְחָק, וְיִצְחָק נִתְגַּדֵּל בּוֹ. שֶׁנֶּאֱמַר "וַיֵּלְכוּ שְׁנֵיהֶם יַחְדָּו", וּכְתִיב אַבְרָהָם הוֹלִיד אֶת יִצְחָק, וְכִי לֹא הוֹלִיד אֶלָּא יִצְחָק, אֶלָּא שֶׁנִּתְגַּדֵּל בּוֹ.
