The tongue is a fire

We need to check the source if we feel that we have an untamed tongue.
What kind of wisdom have we acquired?
There are 2 kinds of wisdom: One descends from above and the other one does not descend from above.
The wisdom that is from above is first pure, then peaceable, gentle, willing to yield, full of mercy and good fruits, without partiality and without hypocrisy.
The wisdom does not descend from above is earthly, sensual, demonic. For where envy and self-seeking exist, confusion and every evil thing are there.
If we want to tame our tongue, we need to get wisdom that is from above which is from God.
