Titus 1:9-11

AKJV(i) 9 Holding fast the faithful word as he has been taught, that he may be able by sound doctrine both to exhort and to convince the disputers. 10 For there are many unruly and vain talkers and deceivers, specially they of the circumcision: 11 Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre's sake.
