זֹ֣את בְּרִיתִ֞י אֲשֶׁ֣ר תִּשְׁמְר֗וּ בֵּינִי֙ וּבֵ֣ינֵיכֶ֔ם וּבֵ֥ין זַרְעֲךָ֖ אַחֲרֶ֑יךָ הִמּ֥וֹל לָכֶ֖ם כָּל־זָכָֽר׃
Esta é a Minha aliança que guardareis entre Mim e vós, e a tua descendência depois de ti: Circuncidareis todo macho entre vós.
Shenei Luchot HaBerit
This portion contains the positive commandment that males should be circumcised. The Torah says: זאת בריתי אשר תשמור ביני וביניכם ובין זרעך אחריך המול ימול כל זכר. This commandment is repeated in Parshat Tazria where the Torah says: ביום השמיני ימול בשר ערלתו. There are many commandments which are recorded twice in the Torah. There is always a compelling reason for this, as our sages have demonstrated.
