Zamzummim

Boyd’s Bible Dictionary:

An Ammonite name for a race of Rephaim or giants (Deut. 2:20).

“Zamzummims” From Concise Bible Dictionary:

See Zuzims.

“Zuzims, Zamzummims” From Concise Bible Dictionary:

A giant race who inhabited the district afterward held by the Ammonites: they were smitten early by Chedorlaomer. The meaning of the term is doubtful: Gesenius says the first name is perhaps from the fertility of their country, and the second signifies “noisy nations.” Fürst judges the first to signify “prominent ones, giants,” and the second “powerful, vigorous” (Gen. 14:5; Deut. 2:20).
