Popular compendium of kabbalistic and aggadic interpretations on the weekly Torah reading by R. Abraham Reuben ben Hoeshke Katz (d. 1673). The text is in two columns in block type. It is on the Torah only, R. Reuben's intent to extend it to the Megillot not being realized. The contents are based on a large variety of Midrashic and kabbalistic sources, a number no longer extant or existing only in fragments. R. Reuben intermingles kabbalah, halakhot and aggadah, but does not add original material of his own.

Examples of entries are,

     "For indeed I was stolen away from the land of the Hebrews" (Genesis 40: 15). When the Holy One, blessed be He, came to give the Torah to the Ishmaelite       (Arab) nation they said to Him, what is written in it? He responded, "You shall not steal" (Exodus 20:13). They answered, we cannot abandon the ways of our fathers who stole Joseph, sold him and brought him down to Egypt, as it says, "For indeed I was stolen away from the land of the Hebrews" (Pirkei Rabbi Eliezer)

     "the chief baker" (Genesis 40:16). He is a resurrection of the soul of Cain, and "Cain shall be avenged sevenfold" (Genesis 4:24) white baskets alluding to the nullification of the Temple offerings, white חורי being the letters of "sweet savor" ריח נחוח. Then he nullified one hundred candles, equal to the number of baskets סלי. (Gali Raza).

     And Joseph went down to Egypt and they accepted him and made him a ruler, as it says, "And Joseph was the governor" (Genesis 42:6). They honored Jacob, as it says, "the Egyptians mourned for him seventy days" (Genesis 50:3). The Holy One, blessed be He said, what honor can I give the Egyptians?
He called it by the name of Gan Eden one time, "like the garden of the Lord, like the land of Egypt" (Genesis 13:10). When they turned and enslaved them (the Jews) He turned from this honor and said I will make it desolate, as it says, "Egypt shall be a desolation" (JoeI4:19). (Midrash Rabbah Bo).

Yalkut Re'uveni was placed on the Index librorum prohibitorum, remaining there until the last edition of that work in 1948.
