Midrash su Salmi 61:6

"For thou, O Lord, hast made me glad through thy work" (Ps. 92:4). Adam said: The Holy One, blessed be He, had made me glad and brought me into the garden of Eden, and showed me the place of the abode of the righteous in the garden of Eden, and He showed me the four kingdoms, their rule and their destruction; and He showed me David, the son of Jesse, and his dominion in the future that is to come. I took from my years seventy years and added them to his days, as it is said, "Thou wilt add days to the days of the king; his years shall be as many generations" (Ps. 61:6). The Holy One, blessed be He, said to him: Thou wilt add days to the days of (the king Messiah); I also will add to his years in the future which is to come, as though they were many generations, as it is said, "His years shall be as many generations" (ibid.). I have given to God praise, and song (lauding) His works, as it is said, "I will sing of the works of thy hands" (Ps. 92:4).

[(Gen. 35:9, 11:) NOW GOD APPEARED UNTO JACOB AGAIN]… < AND GOD SAID TO HIM: I AM GOD ALMIGHTY >. This text is related (to … Ps. 61:6 [5]): FOR YOU, O GOD, HAVE HEARKENED TO MY VOWS; < YOU HAVE GRANTED THE HERITAGE OF THOSE WHO FEAR YOUR NAME >. Isaac had a face with a visage like < that of > his father.⁸²Gk.: prosopon. On Isaac’s face being like that of Abraham, see Targum Pseudo-Jonathan, Gen. 25:19; BM 87a. (Gen. 25:19:) THESE ARE THE GENERATIONS OF ISAAC BEN ABRAHAM: ABRAHAM SIRED ISAAC. What is the meaning of ABRAHAM SIRED ISAAC? That he had a face with a visage like that of his father. Ergo (in Ps. 61:6 [5]): YOU HAVE GRANTED THE HERITAGE OF THOSE WHO FEAR YOUR NAME.⁸³According to BM 87a, Isaac’s visage miraculously became like that of Abraham and thereby demonstrated his paternity, i.e., that Isaac had a heritage. Just as Abraham had the Holy One speak with him at the age of ninety-nine years (in Gen. 17:1), so did Jacob have the Holy One speak with him at the age of ninety-nine years. Just as Abraham had the Holy One say to him (in Gen. 17:1): I AM GOD ALMIGHTY; BE FRUITFUL AND MULTIPLY;⁸⁴These last four words are not found in the Masoretic Text. so did JACOB have him speak with him as God Almighty. It is so stated (in Gen. 35:9, 11:) NOW GOD APPEARED UNTO JACOB AGAIN … < AND GOD SAID TO HIM >: [I AM GOD ALMIGHTY); BE FRUITFUL AND MULTIPLY.
