John 7:21-23

²¹Jesus answered and said to them, I have done one work, and ye all marvel.

²²Moses therefore gave to you circumcision, (not because it is from Moses, but from the fathers) and ye on the sabbath circumcise a man.

²³If a man on the sabbath receiveth circumcision, that the law of Moses should not be broken; are ye angry at me, because I have restored a man to sound health on the sabbath?
