Titus 3:10
Reject a divisive man after a first and second admonition,
What it says
A divisive person is to be warned once and then a second time, and after that rejected.
What it is doing
It gives Titus the pattern for dealing with division.
In context
9But avoid foolish controversies, genealogies, arguments, and quarrels about the law, because these things are pointless and worthless. 10Reject a divisive man after a first and second admonition, 11knowing that such a man is corrupt and sinful; he is self-condemned.
