James 3:11

9 With the tongue we bless our Lord and Father, and with it we curse men, who have been made in God’s likeness.

10 Out of the same mouth come blessing and cursing. My brothers, this should not be!

Can both fresh water and salt water flow from the same spring?

12 My brothers, can a fig tree grow olives, or a grapevine bear figs? Neither can a salt spring produce fresh water.

13 Who is wise and understanding among you? Let him show it by his good conduct, by deeds done in the humility that comes from wisdom.

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