Ecclesiastes 1:16

Futility of Secular Wisdom

1:16 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.”

Ecclesiastes 10:20

10:20 Do not curse a king even in your thoughts,

and do not curse the rich while in your bedroom;

for a bird might report what you are thinking,

or some winged creature might repeat your words.
