Gen 17:23

וַיִּקַּ֨ח אַבְרָהָ֜ם אֶת־יִשְׁמָעֵ֣אל בְּנ֗וֹ וְאֵ֨ת כָּל־יְלִידֵ֤י בֵיתוֹ֙ וְאֵת֙ כָּל־מִקְנַ֣ת כַּסְפּ֔וֹ כָּל־זָכָ֕ר בְּאַנְשֵׁ֖י בֵּ֣ית אַבְרָהָ֑ם וַיָּ֜מָל אֶת־בְּשַׂ֣ר עָרְלָתָ֗ם בְּעֶ֨צֶם֙ הַיּ֣וֹם הַזֶּ֔ה כַּאֲשֶׁ֛ר דִּבֶּ֥ר אִתּ֖וֹ אֱלֹהִֽים׃

On that very day Abraham took his son Ishmael and all those born in his household or purchased with his money—every male among the members of Abraham’s household—and he circumcised them, just as God had told him.
