Hebrews are vagrants?

"Some perhaps were still trying to follow inadequate bicameral voices, or clinging too the edge of settled land, fearing to launch out, becoming breeders of sheep and camels, while others, having struggled unsuccessfully to mingle with more settled peoples, then pushed out into the open desert, where only the ruthless survive, perhaps in precarious pursuit of some hallucinated vision, some back parts of a god, some new city or promised land.

"To the established city-states, these refugees were the desperate outcasts of the desert wilderness. The city people thought of them collectively as robbers and vagrants. And so they often were, either singly, as miserable homeless wretches stealing by night the grapes which the vine-dressers scorned to pick, or as whole tribes raiding the city peripheries for their cattle and produce, even as nomadic Bedouins occasionally do today. The word for vagrants in Akkad, the language of Babylon, is khabiru, and so these desert refugees are referred to on cuneiform tablets. And khabiru, softened in the desert air, becomes hebrew" (pp. 293-294).
