7:22 However, because Moses gave you the practice of circumcision 1 (not that it came from Moses, but from the forefathers), you circumcise a male child 2 on the Sabbath.
1 tnGrk “gave you circumcision.”
2 tnGrk “a man.” While the text literally reads “circumcise a man” in actual fact the practice of circumcising male infants on the eighth day after birth (see Phil 3:5) is primarily what is in view here.
