John 7:20

He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him.

Did not Moses give you the law, and yet none of you keepeth the law? Why go ye about to kill me?

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

Moses therefore gave unto you circumcision; (not because it is of Moses, but of the fathers;) and ye on the sabbath day circumcise a man.
