Today their helpful prayer off the back of Psalm 59:1-7 is this:
Lord, save me from the sins of my tongue and the flaws of character that fuel them. Make my words honest (by taking away my fear), few (by taking away my self-importance), wise (by taking away my thoughtlessness), and kind (by taking away my indifference and irritability), Amen.
