Titus 1:10
10For there are also many unruly men, vain talkers and deceivers, especially those of the circumcision,
For: this is why the overseer must be able to rebuke. Many are unruly, vain talkers and deceivers, especially those of the circumcision. Wesley: they of the circumcision—the Jewish converts.
Insubordination and empty talk are not small interior faults; they deceive. The circumcision party names a pressure toward myths and commands that turn from the truth. Sound doctrine in v. 9 has a present enemy.
The for ties v. 9’s rebuke to a crowded field of insubordinate talkers, especially of the circumcision.
Empty talk is not harmless. Deceivers, many of them, unsettle the church from a Judaizing angle. God provides elders with two voices because wolves are already in the towns.
