Titus 3:14

And let our people also learn to maintain good works, to meet urgent needs, that they may not be unfruitful.

We must learn to devote ourselves to doing what is good, in order to provide for urgent needs and not live unproductive lives.

We must learn to do good deeds to meet necessary demands, whatever the occasion may require, so that we will not be unproductive.

Titus 3:10

Reject a divisive man after the first and second admonition, 11 knowing that such a person is warped and sinning, being self-condemned.

Warn a divisive person once, and then warn them a second time. After that, have nothing to do with them.

After a first and second warning reject a divisive man, who promotes heresy and causes dissension—ban him from your fellowship and have nothing more to do with him.

You may be sure that such people are warped and sinful; they are self-condemned.
You may be well aware that such a person is twisted and is sinning; he is convicted and self-condemned and is gratified by causing confusion among believers.

Titus 3:9

But avoid foolish disputes, genealogies, contentions, and strivings about the law; for they are unprofitable and useless.

Avoid foolish controversies and genealogies and arguments and quarrels about the law, because these are unprofitable and useless.

Avoid foolish and ill-informed and stupid controversies and genealogies and dissensions and quarrels about the Law, for they are unprofitable and useless.
