Genesis
Chapters 49:1-4
King James Version, American Edition
1And Jacob called unto his sons, and said, Gather yourselves together, that I may tell you that which shall befall you in the last days.
2Gather yourselves together, 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 excel;because thou wentest up to thy father's bed;then defiledst thou it: he went up to my couch.
