'Thought' in the Bible

He will not give much thought to the days of his life; because God lets him be taken up with the joy of his heart.

Give thought to the work of God. Who will make straight what he has made bent?

In the day of wealth have joy, but in the day of evil take thought: God has put the one against the other, so that man may not be certain what will be after him.

Whatever comes to your hand to do with all your power, do it because there is no work, or thought, or knowledge, or wisdom in the place of the dead to which you are going.
