Boyd’s Bible Dictionary:
(splendor). The Philistine giant who defied the army of Israel (1 Sam. 17:4-54). Another Goliath (2 Sam. 21:19-22).
Concise Bible Dictionary:
The giant of Gath, who for forty days defied the armies of Israel. He was slain by David with a sling and a stone in the name of Jehovah. David cut off his head and carried it to Jerusalem. Goliath’s sword was preserved and eventually restored to David. His height was six cubits and a span, about 8' 4" by the shortest cubit. He was a type of Satan, too strong for any to conquer except the one in the power of Jehovah, David being a type of the Lord Jesus (1 Sam. 17:4-23; 1 Sam. 21:9). Goliath’s brother, named Lahmi, also a giant, is evidently the one spoken of in 2 Samuel 21:19 (compare 1 Chron. 20:5).
