'Circumcise' in the Bible

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

And {at eight days of age} you shall yourselves circumcise every male [belonging] to your generations [and] {the servant born in your house and the one bought from any foreigner} who is not from your offspring.

{You must certainly circumcise} {the servant born in your house and the one bought from any foreigner}. And my covenant shall be with your flesh as an everlasting covenant.
