Mattityahu 12:34-36

Orthodox Jewish Bible

³⁴ You banim of nechashim (sons of snakes), how are you able to speak tovot (good things), for out of the abundance of the lev (heart) the mouth speaks.

³⁵ The ish tov (good man) out of the good otzar (treasure) brings forth good; and the ish rah out of the evil otzar brings forth evil.

³⁶ But I say to you, that for every careless lashon horah (evil speech) that men speak, they will be called to account on the Yom HaDin (the Day of Judgment).
