Mattityahu 12:33-35

Orthodox Jewish Bible

³³ Either make the etz (tree) tov (good) and its pri (fruit) will be tov, or make the etz nishchat (corrupt) and its pri will be rah; for by its pri the etz is known.

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.
