Genesis 3:6-7

Then the woman saw that the tree was good for food and delightful to look at, and that it was desirable for obtaining wisdom. So she took some of its fruit and ate it; she also gave some to her husband, who was with her, and he ate it. Then the eyes of both of them were opened, and they knew they were naked; so they sewed fig leaves together and made loincloths for themselves.
