Genesis 49:3-7

3“Reuben, you are my firstborn; My might, the beginning of my strength and vigor, Preeminent in dignity and preeminent in power [that should have been your birthright].

4But unstable and reckless and boiling over like water [in sinful lust], you shall not excel or have the preeminence [of the firstborn], Because you went up to your father’s bed [with Bilhah]; You defiled it—he went up to my couch.

5“Simeon and Levi are brothers [equally headstrong, deceitful, vindictive, and cruel]; Their swords are weapons of violence and revenge.

6O my soul, do not come into their secret council; Let not my glory (honor) be united with their assembly [for I knew nothing of their plot]; Because in their anger they killed men [an honored man, Shechem, and the Shechemites], And in their self-will they lamed oxen.

7Cursed be their anger, for it was fierce; And their wrath, for it was cruel. I will divide and disperse them in Jacob, And scatter them in [the midst of the land of] Israel.
