Targum su Genesi 49:1

And Jakob called his sons and said to them, Purify yourselves from uncleanness, and I will show you the hidden mysteries, the ends concealed, the recompense of reward for the righteous, the retribution of the wicked, and the bower of Eden, what it is. And the twelve tribes of Israel gathered themselves together around the golden bed whereon he reclined, and where was revealed to him the Shekina of the Lord, (though) the end for which the king Meshiha is to come had been concealed from him. Then said he, Come, and I will declare to you what shall befall you at the end of the days.

And our father Jakob called his sons, and said to them, Gather together, and I will teach yon the concealed end, the secret mysteries, the recompense of reward for the just, and the punishment of the wicked, and the blessedness of Eden, what it is. And the twelve tribes of Jakob assembled and surrounded the golden bed whereon our father Jakob lay, desiring that he should teach them (at the) end in benediction and consolation. Then was revealed to him the secret that had been hidden from him, and then was opened the door which had been shut to him. Our father Jakob turned therefore and blessed his sons, every man according to his good did he bless him. When the twelve tribes of Jakob were assembled, and surrounded the golden bed whereon our father Jakob lay, they expected that he would make known to them the order of blessing and consolation: but they were hidden from him. Our father Jakob answered and said to them: From Abraham my father’s father arose the profane Ishmael and all the sons of Keturah; and from Izhak my father arose the profane Esau, my brother; and I am afraid lest there should be among you a man whose heart is separated from his brethren to go and worship before strange idols. The twelve tribes of Jakob answered all together, and said, HEAR US, ISRAEL OUR FATHER! THE LORD OUR GOD IS ONE LORD! And Jakob our father answered, and said, May His Great Name be blessed for ever and ever!
