Ecclesiastes 10:17

10:17 Blessed are you, O land, when your king is the son of nobility,

and your princes feast at the proper time – with self-control and not in drunkenness.

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.
