Titus

1. Titus 1:7
   For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre;
2. Titus 1:11
   Whose mouths must be stopped, who subvert whole houses, teaching things which they ought not, for filthy lucre’s sake.
