Genesis 49:3-5 New Revised Standard Version (NRSV)
3 Reuben, you are my firstborn,
my might and the first fruits of my vigor,
excelling in rank and excelling in power.
4 Unstable as water, you shall no longer excel
because you went up onto your father’s bed;
then you defiled it—you went up onto my couch!
5 Simeon and Levi are brothers;
weapons of violence are their swords.
