Kabbalah Mazmur 8:6: Pardes Rimmonim

יובל (Yovel/Yuval) is Binah (Understanding). And she is called this way because she completes the fiftieth year in the secret of the Fifty Gates [of Understanding], and she is the fiftieth year, which is the gate that is more marvellous than Moses our teacher, may he rest in peace, as you say (Psalms 8:6): “You have made him a little less [מעט] than divine” [in the Babylonian Talmud, tractate Rosh Hashanah 21b this verse is applied to Moses]. You should not say מעט but מ"ט [which has the numerical value of 49, thus one less than 50] etc. And this degree [Binah] is called by this name [יובל] when she flows into the fifty gates and gives an influx of abundance and good. And this is the meaning of Yuval, as “and towards a stream [יובל, Yuval] it will extend its roots” (Jeremiah 17:8). And as it will revolve until it has reached the fiftieth gate then in/through it [the fiftieth gate] it will cling to Chochmah (Wisdom). And on this it is said to Moses: “Be silent, thus [כך] it has come up in thought” [Babylonian Talmud, tractate Menachot 29b]. כך is in Gematria 40 [the text reads נ', 50, which is probably a mistake for מ', 40], while silence is in Chochmah which is Yod [י', 10]. And it has come up in thought which is Chochmah. [thus the verse “Be silent, thus it has come up in thought” refers to the fiftieth Gate of Understanding as it counts 10 (Be silent) + 40 (thus) = 50, ascending to Chochmah]. And because of this he [Moses] did not grasp the subject of the death of Rabbi Aqiva [as Moses had attained to only the fourty-ninth Gate of Understanding], because his death was on the side of the judgement, in the secret of the ascent, as will be explained in the Gate of the Soul [Gate 31 of the Pardes Rimonim], chapter 5. And we will return to our subject that in the cleaving of this gate to Chochmah, then it [this gate] is Yuval and then the whole world is mercy and great abundance, liberty and deliverance, and then we will call this degree [Binah] Yovel/Yuval.
