Using context clues during bible study can develop critical thinking skills in the student. When applying context clues the traditional interpretation of Genesis chapter 3 suggest the fruit of the tree of knowledge is the fig.
Genesis 3:5-7
King James Version
5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
7 And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.
Based on the text do you think they picked and apple, fig or another fruit.
