HESH'MON (fertility), a town named with others as lying in the south of Judah, Josh 15:27. Wilton connects it with Husham, an Edomite king, Gen 36:34-35, and with 'Ain Hash, perhaps Hashmonah of Num 33:29-30, but Conder identifies Heshmon with a site called el-Meshash ("the pits"), which has two wells and is on the road from Beer-sheba to Moladah.
