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.
David and Jonathan
Susan Ackerman also believes that there is highly eroticized language present in six different sections in the Hebrew Bible in regards to the relationship of David and Jonathan. The six sections she mentions are 1) David and Jonathan's first meeting in 1 Sam. 18:1-18:4 2) the most important description of David and Jonathan's first few meetings in 1 Sam 19:1-19:7. 3) the incident of Saul berating Jonathan for his friendship with David in 1 Sam 20:30-20:34 4) David fleeing from the court of King Saul in 1 Sam. 20:1-20:42 5) the description of David and Jonathan's final meeting in 1 Sam. 23:15-23:18 and 6) David's lament (the Song of the Bow) for Saul and Jonathan. Of these six examples, Ackerman identifies the most important example being the last one (the Song of the Bow) due to David's assertion that Jonathan's love to David "was more wonderful than the love of women".
