Ecclesiastes 6:12

12 For who knows what is good for a man during his lifetime, during the few years of his futile life? He will spend them like a shadow. For who can tell a man what will be after him under the sun?

Ecclesiastes 8:7

7 If no one knows what will happen, who can tell him when it will happen?

Ecclesiastes 10:14

14 Yet the fool multiplies words. No man knows what will happen, and who can tell him what will come after him?

Ecclesiastes 10:20

20 Furthermore, in your bedchamber do not curse a king, and in your sleeping rooms do not curse a rich man, for a bird of the heavens will carry the sound and the winged creature will make the matter known.
