And when yam (sea) adds up to fifty, this is the meaning of: (Ps. 93:3)... the rivers shall raise their pounding (dokhyam) – with a switching of the letters of DoKh (pounding) – and it is KhaD (pitcher).
And DaKh is the Righteous-One with this pitcher, because it is broken (tavira) in exile. The Shekhinah, who is the pitcher, upon it is stated: (Ps. 51:19)... a broken and depressed (niDKeh) heart, ELQYM do not despise.
The Righteous-One (Yesod) is pounding (dakh) in the water of the Torah, and He is crushed (katit) in the oil of the Torah. It is this that is written: (Num. 28:5) crushed oil. When? When the Vav ו is removed from Hei ה, and She remains Dalet ד. Dalat (poor) certainly! And because of this, the amount of ‘crushed’ oil is a quarter of a hin – a quarter of the letter HEi ה specifically, For She has reverted to DaLeT ד. And that which is ‘crushed’ (katit) is the lesser Vav ו, the completion of Hei ה.
