nTitus 3:10-11
(NIV) Warn a divisive person once, and
then warn him a second time. After that,
have nothing to do with him. 11 You may be
sure that such a man is warped and sinful;
he is self-condemned.
nGalatians 5:15
(NIV) If you keep on biting and
devouring each other, watch out or you will
be destroyed by each other.
