Parallel
Ecclesiastes 10:20
Brenton's English Septuagint · Berean Standard Bible
Even in thy conscience, curse not the king; and curse not the rich in thy bedchamber: for a bird of the air shall carry thy voice, and that which has wings shall report thy speech.
Do not curse the king even in your thoughts, or curse the rich even in your bedroom, for a bird of the air may carry your words, and a winged creature may report your speech.
