Genesis 17:13 DBY

¹¹  And ye shall circumcise the flesh of your foreskin; and [that] shall be a sign of the covenant between me and you.

¹²  And at eight days old shall every male in your generations be circumcised among you -- he who is born in the house, and he who is bought with money, any stranger who is not of thy seed.

¹³  He who is born in thy house, and he who is bought with thy money, must be circumcised; and my covenant shall be in your flesh for an everlasting covenant.

¹⁴  And the uncircumcised male who hath not been circumcised in the flesh of his foreskin, that soul shall be cut off from his peoples: he hath broken my covenant.

¹⁵  And God said to Abraham, [As to] Sarai thy wife, thou shalt not call her name Sarai, but Sarah shall be her name.
