Cushan appears only in Habakkuk 3:7, where the prophet's theophanic vision describes 'the tents of Cushan in affliction' parallel to 'the curtains of Midian' trembling. The poetic parallelism links Cushan with Midian, suggesting a people or region in similar territory—likely northwestern Arabia or Sinai. The Greek Septuagint translates it as 'Ethiopians,' but the Midian parallel argues for a location much closer to ancient Israel. The name may be a variant or poetic form related to Cush, used here to evoke nomadic peoples affected by God's awesome appearance.
