'Careful' in the Bible

And he said unto him, Say now unto her, Behold, thou hast been careful for us with all this care; what is to be done for thee? wouldest thou be spoken for to the king, or to the captain of the host? And she answered, I dwell among mine own people.

For he shall be as a tree planted by the waters, and that spreadeth out her roots by the river, and shall not see when heat cometh, but her leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit.

Shadrach, Meshach, and Abednego, answered and said to the king, O Nebuchadnezzar, we are not careful to answer thee in this matter.

And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things:

Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.

But I rejoiced in the Lord greatly, that now at the last your care of me hath flourished again; wherein ye were also careful, but ye lacked opportunity.

This is a faithful saying, and these things I will that thou affirm constantly, that they which have believed in God might be careful to maintain good works. These things are good and profitable unto men.
