Genesis
Chapters 49:1-4
English Revised Version
1And Jacob called unto his sons, and said: Gather yourselves together, that I may tell you that which shall befall you in the latter days.
2Assemble yourselves, and hear, ye sons of Jacob; And hearken unto Israel your father.
3Reuben, thou art my firstborn, my might, and the beginning of my strength; The excellency of dignity, and the excellency of power.
4Unstable as water, thou shalt not have the excellency; Because thou wentest up to thy father's bed: Then defiledst thou it: he went up to my couch.
