This proverb uses the metaphor of food and harvest: the words we speak produce a kind of fruit that we ourselves must consume. Good words produce good fruit — satisfaction, blessing, reward. Bad words produce bitter fruit that we must swallow. Our speech is not neutral; it shapes our own life as much as others' lives.
Memory phrase: Words come back to you.
Talk about it: Have your words ever come back to hurt you?
Prayer: God, help me speak words that produce good fruit.
