James 1:19-21, 26

This you know, my beloved brethren. But everyone must be quick to hear, slow to speak and slow to anger; for the anger of man does not achieve the righteousness of God. Therefore, putting aside all filthiness and all that remains of wickedness, in humility receive the word implanted, which is able to save your souls.

If anyone thinks himself to be religious, and yet does not bridle his tongue but deceives his own heart, this man’s religion is worthless.
