Genesis 49:2

^3-4 Reuben, you’re my firstborn,
        my strength, first proof of my manhood,
        at the top in honor and at the top in power,
    But like a bucket of water spilled,
        you’ll be at the top no more,
    Because you climbed into your father’s marriage bed,
        mounting that couch, and you defiled it.

^5-6 Simeon and Levi are two of a kind,
        ready to fight at the drop of a hat.
    I don’t want anything to do with their vendettas,
        want no part in their bitter feuds;
    They kill men in fits of temper,
        slash oxen on a whim.
