Douay-Rheims 1899 American Edition

⁹ Again God said to Abraham: And thou therefore shalt keep my covenant, and thy seed after thee in their generations.

¹⁰ This is my covenant which you shall observe, between me and you, and thy seed after thee: All the male kind of you shall be circumcised:

¹¹ And you shall circumcise the flesh of your foreskin, that it may be for a sign of the covenant between me and you.
