'Careful' in the Bible

Be careful therefore how you hear. For whoever has, to him will be given; and whoever doesn't have, from him will be taken away even that which he thinks he has."

Be careful. If your brother sins against you, rebuke him. If he repents, forgive him.

"So be careful, or your hearts will be loaded down with carousing, drunkenness, and cares of this life, and that day will come on you suddenly.
