Genesis 3:6-7

And when the woman saw that the tree was good for food, and that it was delightful to look at, and a tree to be desired in order to make one wise and insightful, she took some of its fruit and ate it; and she also gave some to her husband with her, and he ate. Then the eyes of the two of them were opened [that is, their awareness increased], and they knew that they were naked; and they fastened fig leaves together and made themselves coverings.
