Verses with the word careful in the Old Testament (3 verses):
2 Kings 4:13
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.
