2 Samuel 21:19. Father of Elhanan, a Bethlehemite, who slew Goliath (KJV "the brother of Goliath," to accord with 1 Chronicles 20:5 and not to contradict 1 Samuel 17 where David kills Goliath). But the true reading is 1 Chronicles 20:5; "Elhanan, the son of Jair, slew Lahmi (eth Lahmi being altered into Βethlehemi ), the brother of Goliath (eth Goliath being substituted for ahiy Goliath ). The change was the more readily made as Lahmi's spear is described exactly as Goliath's (1 Samuel 17:7). (See ELHANAN.) Oregim, "weavers," is a transcriber's accidental interpolation after "Jair," taken from the latter part of the verse. The ancient versions agree with the present Hebrew text, which shows the error is of very ancient date.
