'Be Careful' in the Bible

And then Jesus said to him: "Be careful not to say a word to any one, but go and show yourself to the Priest, and offer the gift directed by Moses, as evidence of your cure."

"Be careful not to say anything to any one; but go and show yourself to the Priest, and make the offerings for your cleansing directed by Moses, as evidence of your cure."

However, for you individually, let each love his wife as if she were himself; and the wife be careful to respect her husband.

How true that saying is! And it is on these subjects that I desire you to lay especial stress, so that those who have learned to trust in God may be careful to devote themselves to doing good. Such subjects are excellent in themselves, and of real use to mankind.

Be careful, Brothers, that there is never found in any one of you a wicked and faithless heart, shown by his separating himself from the Living God.
