WASHPOT — a pot used for washing or bathing. The psalmist declared, “Moab is my washpot” (Ps. 60:8; 108:9; washbasin, NIV, NRSV; washbowl, NASB, REB). The meaning is that Moab (with its sea, the Dead Sea) is to be despised and held in contempt, like a washpot in which soiled hands and feet are washed.
