The familiar proverb “blood is thicker than water” is commonly used to say family bonds are especially strong. The episode also introduces “thick as thieves,” “through thick and thin,” and “from cradle to grave.” The lesson focuses on how people use these expressions today and separates that usage from claims about a proverb’s original wording.
Cultural note: The VOA story presents “the blood of the covenant is thicker than the water of the womb” as the original wording. Treat that as an origin claim, not established historical fact; the lesson does not repeat it as a proven Bible quotation. Also, family loyalty is a social value, not a universal rule that should override safety, consent, or chosen relationships.
