Kabbalah su Isaia 32:78

Rabbi Yosey opened [with the verse] "Happy are those who sow on all waters and let loose the feet of the ox and the donkey" (Isaiah 32:20). [What is] 'Happy are you, who sow on all waters'? We learn there: waters and waters are found. Israel were guiltless, they did not have seed, rather 'by the water' as it is written "and they encamped there by the water" they were under the branches of the Tree of the Holy Blessed One.

In the Secrets of Letters of King Shelomo, he says that the four letters Aleph, Chet, Hei and Ayin were crowned with the four letters Gimel, Yud, Caf and Kof in the palate (as said in Mishpatim, section 532). Therefore, there is an allusion to three columns in the palate as well, as said, “the palate tastes food” (Iyov 34:2) referring to the right column; “Can that which is unsavory be eaten without salt?” (Ibid. 6:6) referring to the left column that we must not enjoy before it unites with the right, like the “unsavory without salt.” The verse, “And the work of righteousness shall be peace” (Yeshayahu 32:17) is the central column that unites and makes peace between the two columns, right and left. “More to be desired are they than gold, even much fine gold; sweeter” (Tehillim 19:11) refers to Malchut that receives the abundance of the three columns that are surely sweet.
