Goliath: great. (1.) A famous giant of Gath, who for forty days openly
defied the armies of Israel, but was at length slain by David
with a stone from a sling (1 Sam. 17:4). He was probably
descended from the Rephaim who found refuge among the
Philistines after they were dispersed by the Ammonites (Deut.
2:20, 21). His height was "six cubits and a span," which, taking
the cubit at 21 inches, is equal to 10 1/2 feet. David cut off
his head (1 Sam. 17:51) and brought it to Jerusalem, while he
hung the armour which he took from him in his tent. His sword
was preserved at Nob as a religious trophy (21:9). David's
victory over Goliath was the turning point in his life. He came
into public notice now as the deliverer of Israel and the chief
among Saul's men of war (18:5), and the devoted friend of
Jonathan.
(2.) In 2 Sam. 21:19 there is another giant of the same name
mentioned as slain by Elhanan. The staff of his apear "was like
a weaver's beam." The Authorized Version interpolates the words
"the brother of" from 1 Chr. 20:5, where this giant is called
Lahmi.
