2 Corinthians 11:13

οἱ γὰρ τοιοῦτοι κ. τ. λ.: for such men (this explains the ground of his determination in 2 Corinthians 11:12 not to give opportunity for cavil) are false apostles (cf. Revelation 2:2. This speedy appearance of false teachers was one of the most remarkable features of the Apostolic age; cf. Galatians 2:4; Philippians 1:15; Philippians 3:18; Titus 1:10; 2 Peter 2:1; 1 John 4:1), crafty workers (cf. Philippians 3:2), fashioning themselves into Apostles of Christ, i.e., laying special claim to that great title (cf. chap. 2 Corinthians 10:7). μετασχηματίζειν τι is to change the outward appearance (σχῆμα) of a thing, the thing itself in essence (μορφή) remaining unchanged (see reff.).
