The Book of Wisdom 1:8-11

Therefore no one who utters wicked things can go unnoticed, nor will chastising condemnation pass him by.
For the devices of the wicked man shall be scrutinized, and the sound of his words shall reach the LORD, for the chastisement of his transgressions;
Because a jealous ear hearkens to everything, and discordant grumblings are no secret.
Therefore guard against profitless grumbling, and from calumny withhold your tongues;
For a stealthy utterance does not go unpunished, and a lying mouth slays the soul.
