 Zamzummims
    a race of giants; "a people great, and many, and tall, as the
    Anakims" (Deut. 2:20, 21). They were overcome by the Ammonites,
    "who called them Zamzummims." They belonged to the Rephaim, and
    inhabited the country afterwards occupied by the Ammonites. It
    has been conjectured that they might be Ham-zuzims, i.e., Zuzims
    dwelling in Ham, a place apparently to the south of Ashteroth
    (Gen. 14:5), the ancient Rabbath-ammon.

 Zamzummims, projects of crimes; enormous crimes
