Paradox #1
The contradiction in Genesis 27:21 could arise from the act of deception. In this story, Jacob pretends to be his brother Esau to receive a blessing from their father, Isaac. The conflict lies in achieving a positive outcome (receiving a blessing) through dishonest means, which raises questions about integrity and the rightness of using deceit to achieve one's goals.
