'Circumcise' in the Bible
It happened that on the eighth day they came to circumcise the child [as required by the Law], and they intended to name him Zacharias, after his father;
For this reason Moses has given you [God’s law regarding] circumcision (not that it originated with Moses, but with the patriarchs) and you circumcise a man [even] on the Sabbath.
But some from the sect of the Pharisees who had believed [in Jesus as the Messiah] stood up and said, “It is necessary to circumcise the Gentile converts and to direct them to observe the Law of Moses.”
Now they have been told about you, that you are teaching all the Jews who are living among the Gentiles to turn away from [the Law of] Moses, advising them not to circumcise their children or to live according to the [Mosaic] customs.
