'Perish' in the Bible

Food of all kinds is meant for the stomach, and the stomach is meant for food, and God will cause both of them to perish. Yet the body does not exist for the purpose of fornication, but for the Master's service, and the Master exists for the body;

But every competitor in an athletic contest practices abstemiousness in all directions. They indeed do this for the sake of securing a perishable wreath, but we for the sake of securing one that will not perish.
