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, לברית מילה , "for the covenant of circumcision" F8 Seder Tephillot, fol. 197. 1. Ed. Basil. Vid. Kimchi in Mal. iii. 1. ; and so it is said F9 Shemot Rabba, sect. 1. fol. 90. 1. ,

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

and so Abraham begat Isaac, and circumcised him the eighth day ; according to the express command in Genesis 17:12

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