This proverb describes a pattern of providential justice in history: the wicked sometimes end up suffering the very harm they intended for the righteous. God's governance of history means the righteous are not ultimately abandoned to the malice of those who oppose them. This does not mean the righteous never suffer — but wickedness aimed at the righteous can be deflected back onto its source.
Memory phrase: God shields the righteous.
Talk about it: How has God ever protected someone you love from harm?
Prayer: God, protect me when others mean me harm.
