(Devarim, Ibid. 21) "They incited Me with a no-god; they angered Me with their vanities': There are men who serve images, things that can be seen (in themselves), but they serve reflections of things, and not these alone, but (they serve) vapors that rise from pots, viz. "They angered Me with their vanities" (lit., "their vapors").
"And I will anger them with a no-people." Read it not "belo am" ("with a no-people"), but "balui am" ("the dregs of the people"), who are cast out of their houses.
Variantly: Those who come from Barbaria, Tunos, and Mauritania, who walk naked in the marketplace, there being nothing more despicable to the L-rd.
