That also was accounted a land of giants,.... Ammon was so reckoned as well as Moab, De 2:10giants dwelt therein in old time; the Rephaim dwelt there, as they did also in Ashteroth Karnaim, Ge 14:5and the Ammonites call them Zamzummims; they are thought to be the same with the Zuzims in Ge 14:5 who had their name, as Hillerus thinks, from Mezuzah, a door post, from their tall stature, being as high as one; and for a like reason Saph the giant might have his name, 2Sa 21:18.
The word Zamzummims, according to him , signifies contrivers of evil and terrible things; they were inventors of wickedness, crafty and subtle in forming wicked and mischievous designs, which struck terror into people, and made them formidable to them.
