Acts 7:8

And he gave him the covenant of circumcision
Or the covenant, of which circumcision was a sign or token, ( Genesis 17:11 ) . Stephen speaks here in the language of the Jews, who are wont to speak of circumcision after this manner; hence in the Jewish liturgy, there is a collect, (hlym tyrbl) , "for the covenant of circumcision" ^F8; and so it is said ^F9,

``when Joseph died, they made void the "covenant of circumcision":''

and Jacob begat the twelve patriarchs;
the heads of the twelve tribes of Israel.
