Parallel
Ecclesiastes 10:20
Clementine Vulgate · Berean Standard Bible
In cogitatione tua regi ne detrahas, et in secreto cubiculi tui ne maledixeris diviti : quia et aves cæli portabunt vocem tuam, et qui habet pennas annuntiabit sententiam.
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.
