James 3:10-13

From the same mouth come blessing and cursing. My brothers, these things ought not to be so. Does a spring pour forth from the same opening both fresh and salt water? Can a fig tree, my brothers, bear olives, or a grapevine produce figs? Neither can a salt pond yield fresh water. Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom.
