Genesis 3

From Genesis 3:
Verse 6-7

The First Sin done by human

6 So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise, she took of its fruit and ate; and she also gave some to her husband, and he ate.
7 Then the eyes of both were opened, and they knew that they were naked; and they sewed fig leaves together and made themselves aprons.
