Likutei Moharan 49:10/ליקוטי מוהר"ן מ״ט:י׳

110. As for why money is given when they cry “Shabbos,” it is because the Torah of the present has a left and a right—”and in her left hand riches” (Proverbs 3:16). But in the Ancient One there is neither left nor riches (Zohar III, 129a). Because of this, when the Jewish people hear tidings of the Torah of the Ancient One, they give money. For they have no need of money, because in the World to Come there is neither eating nor drinking (Berakhot 17a).

2This is the explanation of: {“Kings of armies flee in haste, and the one dwelling at home distributes the spoils” (Psalms 68:13) . }

3“Kings of armies flee”—this refers to the tzaddikim, who are “His angels, mighty warriors.” They flee speedily and hastily in order to run the course, which is dancing. “And the one dwelling at home distributes the spoils”—and the Jewish people are those who distribute money. This is to show that there is no need for money, and that in the aspect of the Ancient One there is no left side. The first letters of Bayit Techalek Shalal (“home distributes the spoils”) spell ShaBbaT.
