זֹ֣את בְּרִיתִ֞י אֲשֶׁ֣ר תִּשְׁמְר֗וּ בֵּינִי֙ וּבֵ֣ינֵיכֶ֔ם וּבֵ֥ין זַרְעֲךָ֖ אַחֲרֶ֑יךָ הִמּ֥וֹל לָכֶ֖ם כָּל־זָכָֽר׃
This is My covenant, which ye shall keep, between Me and you and thy seed after thee: every male among you shall be circumcised.
Targum Jonathan on Genesis
This is My covenant, that you shall observe between My Word and you, and your sons after you:--Every male of you being circumcised, though he have not a father to circumcise him.
