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.
The Bible and violence
War comes again, David is victorious. Saul again wants to kill David, and he flees with help from his wife. Saul searches for him and slays the inhabitants of the city Nob for aiding David (1 Samuel 22). David defeats the Philistines at Keilah, then flees the city pursued by Saul (1 Samuel 22). David and Saul reconcile. David seeks refuge with Achish, king of Gath, and claims he is raiding Judah but is actually raiding and killing in other places (1 Samuel 27). The Philistines begins a war against Saul. David's wives Ahinoam and Abigail are taken in a raid on Ziklag, but he rescue them (1 Samuel 30). The men of Israel flee before the Philistines, and three of Saul's sons are slain. Saul asks his armour-bearer to kill him, but is refused, so he takes his own life. The armour-bearer also takes his own life. Saul's body is beheaded and fastened to a city-wall by the victorious Philistines, but it is retaken by inhabitants of Jabesh-Gilead (1 Samuel 30).
