וְיִֽתֶּן־לְךָ֙ אֶת־בִּרְכַּ֣ת אַבְרָהָ֔ם לְךָ֖ וּלְזַרְעֲךָ֣ אִתָּ֑ךְ לְרִשְׁתְּךָ֙ אֶת־אֶ֣רֶץ מְגֻרֶ֔יךָ אֲשֶׁר־נָתַ֥ן אֱלֹהִ֖ים לְאַבְרָהָֽם׃
아브라함에게 허락하신 복을 네게 주시되 너와 너와 함께 네 자손에게 주사 너로 하나님이 아브라함에게 주신 땅 곧 너의 우거하는 땅을 유업으로 받게 하시기를 원하노라
Mishneh Torah, Kings and Wars
Circumcision was only commanded of Abraham and his descendents, as it says, “You and your descendents who will follow you throughout the generations” (Genesis 17:9). Ishmael’s descendents are excluded from this Commandment, as it says, “For through Isaac shall your descendents be called yours” (Genesis 21:12). Esau is excluded since Isaac said to Jacob, “and he shall give the blessing of Abraham to you and to your descendents” (Genesis 28:4). Since he, alone, was the descendent of Abraham who stood fast with his religion and his upright ways, it is his progeny who were commanded with circumcision.
