'Circumcise' in the Bible

On the eighth day they went to circumcise the child. They were going to name him Zechariah after his father,

Moses gave you circumcision not that it is from Moses, but from the Patriarchs and so you circumcise a man on the Sabbath.

But they have been told about you that you teach all the Jews living among the gentiles to forsake the Law of Moses, and that you tell them not to circumcise their children or observe the customs.
