Sham´mah (astonishment), one of the three chief of the thirty champions of David. The exploit by which he obtained this high distinction, as described in , is manifestly the same as that which in , is ascribed to David himself, assisted by Eleazar the son of Dodo. The inference, therefore, is that Shammah's exploit lay in the assistance which he thus rendered to David and Eleazar. It consisted in the stand which the others enabled David to make, in a field of lentiles, against the Philistines. Shammah also shared in the dangers which Eleazar and Jashobeam incurred in the chivalric exploit of forcing a way through the Philistine host to gratify David's thirst for the waters of Bethlehem ().
Other persons of this name occur. 2. A son of Reuel (; ). 3. A brother of David (; ), who is elsewhere called Shimeah (; ) and Shimma (). 4. One of David's thirty champions, seemingly distinct from the chief of the same name (). 5. Another of the champions distinguished as Shammah the Harodite; he is called Shammoth in , and Shamhuth in . That three of the thirty champions should bear the same name is somewhat remarkable.
