Genesis 17:22

וּֽלְיִשְׁמָעֵאל שְׁמַעְתִּיךָ הִנֵּה בֵּרַכְתִּי אֹתוֹ וְהִפְרֵיתִי אֹתוֹ וְהִרְבֵּיתִי אֹתוֹ בִּמְאֹד מְאֹד שְׁנֵים־עָשָׂר נְשִׂיאִם יוֹלִיד וּנְתַתִּיו לְגוֹי גָּדֽוֹל

And as for Ishmael, I have heard thee; behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation.

וְאֶת־בְּרִיתִי אָקִים אֶת־יִצְחָק אֲשֶׁר תֵּלֵד לְךָ שָׂרָה לַמּוֹעֵד הַזֶּה בַּשָּׁנָה הָאַחֶֽרֶת

But My covenant will I establish with Isaac, whom Sarah shall bear unto thee at this set time in the next year.’

וַיִּקַּח אַבְרָהָם אֶת־יִשְׁמָעֵאל בְּנוֹ וְאֵת כָּל־יְלִידֵי בֵיתוֹ וְאֵת כָּל־מִקְנַת כַּסְפּוֹ כָּל־זָכָר בְּאַנְשֵׁי בֵּית אַבְרָהָם וַיָּמָל אֶת־בְּשַׂר עָרְלָתָם בְּעֶצֶם הַיּוֹם הַזֶּה כַּאֲשֶׁר דִּבֶּר אִתּוֹ אֱלֹהִֽים

And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham’s house, and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.

וְאַבְרָהָם בֶּן־תִּשְׁעִים וָתֵשַׁע שָׁנָה בְּהִמֹּלוֹ בְּשַׂר עָרְלָתֽוֹ

And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin.
