And before this נב there is the concept of redemption which is associated with Yosef and associated with the concept of addition. This is because redemption is a form of addition, נג particularly when the redemption is as the Possuk says: נד פָדָה בְשָׁלוֹם נַפְשִּׁי מִּקֲרָב לִּי “He redeemed my soul with peace from the battle” נה that there is no war and the redemption is achieved in a peaceful manner. נו

In other words, the unity and connection of Yehudah and Yosef, representing both concepts of ‘study and action’ and of ‘redemption and prayer’, these two are juxtaposed נז and are united with each other. This is the unity נח that will be evident in the future נט לְעוֹלָםוְדָוִּד עַבְדִּי נָשִּיא לָהֶם My servant Dovid ס shall be their prince forever.
