Bozrah. This seems to have been at one time the capital of Edom (see Amos 1:12; Isaiah 34:6; Isaiah 63:1). It was a hill city (comp. on Jeremiah 49:16); a village called Busaira (i.e. little Bozrah) now stands among its ruins.
Perpetual wastes. A phrase characteristic of Jeremiah (see also Jeremiah 25:9) and of the second part of Isaiah (Isaiah 58:12; Isaiah 61:4).
