Ecclesiastes 10:6-7

10:6 Fools are placed in many positions of authority,

while wealthy men sit in lowly positions.

10:7 I have seen slaves on horseback

and princes walking on foot like slaves.

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.
