The just person's mouth is generative — it produces wisdom the way a tree produces fruit. The 'froward' (perverse, twisted) tongue ultimately silences itself through its own destructiveness.
Memory phrase: Just mouths bring forth wisdom.
Talk about it: What does it mean to 'bring forth' wisdom? How does wisdom grow from a person who keeps choosing what is right?
Prayer: God, make my mouth like a fruit tree — growing and bringing forth wisdom for everyone around me.
