The Pulpit Commentary on Titus 1:10

Unruly men for unruly and, A.V. and T.R. Unruly ( ἀνυπότακτοι); see Titus 1:6. Vain talkers ( ματαιολόγοι); only here in the New Testament, not found in the LXX., and rare in classical Greek (see ματαιολογία, 1 Timothy 1:6).

κενολόγος and κενολογία are used in the same sense of "vain, empty, talking." Deceivers—( φρεναπάται); here only in the New Testament, not found in the LXX. or in classical Greek—literally, soul-deceivers, or, as some take St, self-deceivers.

Here the word means "deceivers," whoso character is described in 2 Peter 2:14 as "beguiling unstable souls." They of the circumcision; Judaizing Christians, the most obstinate and difficult adversaries with whom St.

Paul had to cope (see Galatians passim; Philippians 3:2, Philippians 3:3, etc.).
