Elhanan, son of Jair
Elhanan son of Jair-Oregim the Bethlehemite ( "’Elḥānān ben-Ya‘rê ’Ōrəḡîm Bêṯhallaḥmî") appears in 2 Samuel 21:19, where he is credited with killing Goliath. As this contradicts the better-known story in 1 Samuel 17 in which it is the famous David who kills Goliath, the 4th century BC Book of Chronicles explains the second Goliath by saying (20:5) that Elhanan "slew Lahmi the brother of Goliath", possibly constructing the name Lahmi from the last portion of the word "Bethlehemite" (""beit-ha’lahmi"). The King James Bible translators modified 2 Samuel 21:18–19 to make it read as if Elhanan had slain Goliath's brother: "And there was again a battle in Gob with the Philistines, where Elhanan the son of Jaare–oregim, a Beth–lehemite, slew "the brother of" Goliath the Gittite, the staff of whose spear was like a weaver's beam", although the Hebrew text at this point makes no mention of the word "brother"; the medieval Jewish authors of the Targum Jonathan solved the problem by explaining Elhanan as an alternative name for David. However, this makes it difficult to explain why David is called "Elhanan" in verse 19 but consistently "David" in the verses that surround it (15, 16, 17, 21, 22). The most widely accepted explanation is that the storytellers have displaced the deed from the obscure Elhanan to the more famous character, David.
Simpsons Bible Stories
Bart sees himself as King David, who kills Goliath, but has not won the war yet: Nelson is Goliath II, Goliath's son. Goliath II has killed Methuselah (Grampa), David's oldest friend in revenge. In retaliation, David challenges Goliath II, but having no stones to sling at him, David loses and is catapulted from the city. David then meets Ralph, a shepherd, who claims he can kill Goliath II. Ralph dies, which enrages David even more. He then trains to try to slay Goliath. Having to climb up the enormous Tower of Babel beforehand, David manages to kill Goliath by throwing a lit lantern down his throat. Goliath is surprisingly still alive, but is quickly killed by Ralph's gravestone, hurled by Ralph himself, who also had not died. Much to his shock, David is sent to jail as the townspeople claim that Goliath was the best King they ever had, building roads, libraries and hospitals. The dream ends with a title card that reads "A Bart Simpson Dream".
