A.T. Robertson Commentary 2 Corinthians 11:13

"For such men are false apostles, deceitful workers, fashioning themselves into apostles of Christ." — 2 Corinthians 11:13 (ASV)

False apostles (ψευδαποστολο). From ψευδης, false, and αποστολος. Paul apparently made this word (cf. Revelation 2:2). In verse 26 we have ψευδαδελφος, a word of like formation (Galatians 2:4). See also ψευδοχριστο and ψευδοπροφητα in Mr 13:22.

Deceitful (δολιο). Old word from δολος (lure, snare), only here in N.T. (cf. Romans 16:18).

Fashioning themselves (μετασχηματιζομενο). Present middle (direct) participle of the old verb μετασχηματιζω for which see on 1 Corinthians 4:6. Masquerading as apostles of Christ by putting on the outward habiliments, posing as ministers of Christ ("gentlemen of the cloth," nothing but cloth). Paul plays with this verb in verses 13,14,15.
