James 3:13

¹¹ Doth a fountain send forth at the same place sweet water and bitter?

¹² 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.

¹⁴ But if ye have bitter envying and strife in your hearts, glory not, and lie not against the truth.

¹⁵ This wisdom descendeth not from above, but is earthly, sensual, devilish.

Do read the surrounding verses too, because the context often says more than a single verse.
