Chukat: Chapter 7
"Round and round goes the wind"

Rabbi Shimon says that in the title verse it means the wind is the Holy Spirit that circles in two directions to adhere to the body. He refers to the three Patriarchs who are the holy Chariot and says that David is the spirit that was attached to them so that they are a perfectly complete holy Chariot. Rabbi Shimon concludes by saying that all of King Solomon's words are recited in the innermost recesses of the holy chamber because they conceal a much deeper wisdom than people realize.
