James 3:10-13

Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be. Doth a fountain send forth at the same place sweet water and bitter? Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh. Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom.
