OLBGrk;
The particle therefore, or, for this, dia touto, maketh in this verse a great difficulty, what the meaning of it should be. The most probable account of it is, that it belongeth to the former verse, which should end thus, and ye all marvel for this. This indeed maketh all plain; otherwise it is very hard to give an account what force it can have, if we consider it as a note of a cause. Moses gave you circumcision, that is, a law about circumcision; yet that law had not its rise from Moses: the law was given to your father Abraham, Genesis 17:10, long before Moses's time. In obedience to that law, you circumcise a male child, or a proselyte, that is, a man grown, on the sabbath day.
