ALL THE COMFORTS OF HOME. Cave 4, like most of the other caves carved into the marl sandstone hills near Qumran, functioned as a private residence, with its smooth, finely chiseled interior providing bright and well-ventilated (if somewhat spartan) accommodations for the sectarian Jew who called Qumran home.
