זֶ֥רַע יַֽעַבְדֶ֑נּוּ יְסֻפַּ֖ר לַֽאדֹנָ֣י לַדּֽוֹר׃
후손이 그를 봉사할 것이요 대대에 주를 전할 것이며
Midrash Tanchuma
Circumcision is so very important that it takes precedence over the Sabbath. Similarly, circumcision is so important that no child is included in the reckoning of generations until he has been circumcised, as it is said: A seed shall serve him; he shall be counted by the Lord unto the next generation (Ps. 22:31).
