Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.
Death and life (are) in the power of the tongue. "Death and life," both of body and soul; both of the speakers and the hearers.
And they that love it shall eat the fruit thereof. They who delight in constantly using it, whether for good or evil, shall experience corresponding results (James 1:19; James 1:25; James 3:6; James 3:8).
