L’Ecclésiaste 11:2 Cabale : Sha'arei Orah

Now, about the recital of Hallel at the beginning of the new month (Rosh Chodesh), the sages stated that this custom was established because it is a time of Atonement-Kaparah-כפרה,²⁷⁵See the liturgy of the Musaf prayer of Rosh Chodesh. Atonement-Kippur-כיפור in the singular refers to Kingship-Malchut. Also see Zohar III 100b being that the moon was blemished and has been renewed. However, the recital of Hallel for miracles and wonders, and for joyous occasions and goodness, such as the Hallel recited on Passover, Shavuot, and Sukkot; at such times there is the full appearance of the Sefirah of Understanding-Binah. For, about Passover the verse states,²⁷⁶Exodus 13:18 “The children of Israel were armed-Chamusheem-חמשים when they came up from the land of Egypt,”²⁷⁷In the written Torah, the word “armed-Chamushim-חמשים” is written without the Vav-ו and thus also bears the meaning, “fifty-Chameesheem-חמשים,” and refers to the fifty Gates of Understanding-Binah. and with it they were redeemed. About Atzeret [the biblical name for Shavuot] it states,²⁷⁸Leviticus 23:16 “You shall count fifty days,” and this counting-Sefirah brought them to the giving of the Torah. Likewise, with the inclusion of the festival of Shemini Atzeret, the festival of Sukkot is eight days long, and as we already have informed you, this refers to the eight Sefirot counted beginning with the Sefirah of Understanding-Binah to the seven Sefirot below her, as hinted in the verse,²⁷⁹Ecclesiastes 11:2 “Distribute portions to seven, and even to eight.” It thus has been adequately hinted that the fifty and the eight are the same. Those who understand this should contemplate it.
