Ecclesiastes 1:13

13 I applied my mind to study and to explore by wisdom all that is done under the heavens. What a heavy burden God has laid on mankind!

Ecclesiastes 2:3

3 I tried cheering myself with wine, and embracing folly—my mind still guiding me with wisdom. I wanted to see what was good for people to do under the heavens during the few days of their lives.

Ecclesiastes 5:2

2 Do not be quick with your mouth, do not be hasty in your heart to utter anything before God. God is in heaven and you are on earth, so let your words be few.

Ecclesiastes 10:20

20 Do not revile the king even in your thoughts, or curse the rich in your bedroom, because a bird in the sky may carry your words, and a bird on the wing may report what you say.
