James 3:11

but nobody can tame the tongue. It is a restless evil, full of deadly poison.

With it we bless our God and Father, and with it we curse men who are made in the image of God.

Out of the same mouth comes blessing and cursing. My brothers, these things ought not to be so.

Can a fig tree, my brothers, yield olives, or a vine figs? Thus no spring yields both salt water and fresh water.

Who is wise and understanding among you? Let him show by his good conduct that his deeds are done in gentleness of wisdom.

But if you have bitter jealousy and selfish ambition in your heart, don’t boast and don’t lie against the truth.
