Levi

"She (Leah) conceived again and bore a son, and said, “Now this time my husband will become attached to me, because I have borne him three sons.” Therefore his name was called Levi."

"Now it came to pass on the third day, when they were in pain, that two of the sons of Jacob, Simeon and Levi, Dinah’s brothers, each took his sword and came boldly upon the city and killed all the males. And they killed Hamor and Shechem his son with the edge of the sword, and took Dinah from Shechem’s house, and went out. The sons of Jacob came upon the slain, and plundered the city, because their sister had been defiled. They took their sheep, their oxen, and their donkeys, what was in the city and what was in the field, and all their wealth. All their little ones and their wives they took captive; and they plundered even all that was in the houses."

"“Simeon and Levi are brothers"
