Genesis 49:5

2 Assemble yourselves, and hear, ye sons of Jacob: and hearken to Israel your father.

3 Reuben, thou [art] my first-born, my might, and the beginning of my strength, the excellence of dignity, and the excellence of power:

4 Unstable as water, thou shalt not excel; because thou wentest up to thy father's bed; then defiledst thou [it]; he went up to my couch.

5 Simeon and Levi [are] brethren: instruments of cruelty [are in], their habitations.

6 O my soul, come not thou into their secret; to their assembly, my honor, be not thou united: for in their anger they slew a man, and in their self-will they digged down a wall.

7 Cursed [be] their anger, for [it was] fierce: and their wrath, for it was cruel: I will divide them in Jacob, and scatter them in Israel.

8 Judah, thou [art he] whom thy brethren shall praise; thy hand [shall be] on the neck of thy enemies: thy father's children shall bow down before thee.
