Watch out for the "dogs!" [Note: "Dogs" were viewed with disgust by the ancient Jews (Deut. 23:18; II Kings 8:13; Rev. 22:15), so the term is used here derogatorily for Jewish Christians who were trying to impose on the church the requirements of the law of Moses]. Watch out for the evil workers! Watch out for those who mutilate the body meaninglessly! [Note: Paul here alludes, in a derogatory wordplay, to the Jewish practice of circumcision].

[I was] circumcised eight days after I was born; [I am] from the nation of Israelites; from the tribe of Benjamin and of Hebrew ancestry [i.e., an outstanding Hebrew]. As far as the law of Moses is concerned, [I am] a Pharisee [i.e., a strict sect of the Jewish religion].
