giants dwelt therein in old time;
the Rephaim dwelt there, as they did also in Ashteroth Karnaim, ( Genesis 14:5 )
and the Ammonites call them Zamzummims;
they are thought to be the same with the Zuzims in ( Genesis 14:5 ) who had their name, as Hillerus F3 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, ( 2 Samuel 21:18 ) . The word Zamzummims, according to him F4, 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.
