Genesis 49:1-4:
49 And Jacob called his sons and said, “Gather together, that I may tell you what shall befall you in the last days:
2 “Gather together and hear, you sons of Jacob,
And listen to Israel your father.
3 “Reuben, you are my firstborn,
My might and the beginning of my strength,
The excellency of dignity and the excellency of power.
4 Unstable as water, you shall not excel,
Because you went up to your father’s bed;
Then you defiled it—
He went up to my couch.
Deuteronomy 33:1–6:
Moses’ Final Blessing on Israel
33 Now this is the blessing with which Moses the man of God blessed the children of Israel before his death. 2 And he said:
“The Lord came from Sinai,
And dawned on them from Seir;
He shone forth from Mount Paran,
And He came with ten thousands of saints;
From His right hand
Came a fiery law for them.
3 Yes, He loves the people;
All His saints are in Your hand;
They sit down at Your feet;
Everyone receives Your words.
4 Moses [a]commanded a law for us,
A heritage of the congregation of Jacob.
5 And He was King in Jeshurun,
When the leaders of the people were gathered,
All the tribes of Israel together.
6 “Let Reuben live, and not die,
Nor let his men be few.”
