'Thought' in the Bible

I thought to myself, "I have become much wiser than any of my predecessors who ruled over Jerusalem; I have acquired much wisdom and knowledge."

I thought to myself, "Come now, I will try self-indulgent pleasure to see if it is worthwhile." But I found that it also is futile.

I thought deeply about the effects of indulging myself with wine (all the while my mind was guiding me with wisdom) and the effects of behaving foolishly, so that I might discover what is profitable for people to do on earth during the few days of their lives.

So I thought to myself, "The fate of the fool will happen even to me! Then what did I gain by becoming so excessively wise?" So I lamented to myself, "The benefits of wisdom are ultimately meaningless!"

For what hath been to a man by all his labour, and by the thought of his heart that he laboured at under the sun?

I thought to myself, "God will judge both the righteous and the wicked; for there is an appropriate time for every activity, and there is a time of judgment for every deed.

I also thought to myself, "It is for the sake of people, so God can clearly show them that they are like animals.

So I congratulated and thought more fortunate are those who are already dead than the living who are still living.

But better off than either of them is the one who has not yet been born, who has not seen the evil deeds that are done under the sun.

Do not be hasty in word or impulsive in thought to bring up a matter in the presence of God. For God is in heaven and you are on the earth; therefore let your words be few.

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.

Curse not the king, no not in thy thought; and curse not the rich in thy bedchamber: for a bird of the air shall carry the voice, and that which hath wings shall tell the matter.
