Genesis 49:5-7

5 Simeon and Levi are brothers. They use their swords as weapons to destroy people. 6 I will not join them when they decide to do wicked things. I will not meet with them. They have killed people when they are angry. They have been cruel to oxen because it makes them happy. 7 Their anger is so strong that God will curse them. Their anger makes them do cruel things. So God will curse them. I will cause your descendants to divide from each other. They will live everywhere in the country of Israel.
