The Zohar, Chapter “BeShalach (When Pharoah Sent),” Items 466-467: “And Aaron and Hur supported his hands.”… When he raised means that he raised the right over the left. By that, it meant that when he spread his hands, Israel prevailed, Israel above, ZA. “And when he let down his hand, Amalek prevailed.”
The right refers to Hesed (the quality of mercy), and the Light of Hassadim (Mercy) is what we need most. First and foremost the Light of correction, the Light of Hassadim, must reign within us for that is what binds everybody together.
It reigns inside our desire (Kli), covers it with the intention to bestow, and then, to the extent the Kli is corrected by the intention to bestow, the Kli can be clothed by the Light of Hochma (Wisdom), which is the Creator’s presence, His sensation and revelation.
But before the Creator is revealed, we need equivalence with Him. This is done by the Light of Hassadim, the Light of bestowal and mercy (Hessed), filling us at our request.
Therefore, the entire war between Moses and Amalek (Amalek is an abbreviation of Al MenAt LEKabel, “for the sake of receiving”) amounts to Moses initially demanding the Light of Mercy, the force of Hassadim, which is the force of Aaron who supports him from the right. Then Moses begins to raise his heavy hands, called “the hands of faith.” Why are they heavy? It is because his desire to enjoy is great and constantly growing on account of Amalek.
When the desire to enjoy is awakened in a person, his hands, “the hands of faith,” the symbol of bestowal, are lowered, and the intention for himself overcomes him once more. What follows is the necessity to support Moses’ hands.
Hence, the Upper Forces come out against Amalek: the right, Aaron, and the left, Hur, while the Light descends from Above and clothes one’s desire, corrected by faith, the Light of Bina. Then Moses is able to defeat Amalek, his egoism.
This takes place in many situations in our work: The desire to enjoy grows, and we must wage war against it.
