2 Samuel 21:19

And there was again a battle in Gob with the Philistines ,.... Another battle with them in the same place:

where Elhanan the son of Jaareoregim, a Bethlehemite, slew the brother of Goliath the Gittite ; the word "brother" is rightly supplied from 1 Chronicles 20:5 ; where his name is said to be Lahmi, for not Goliath himself was slain, though some so interpret it, and take Elhanan to be David; so Jarchi, and with which agrees the Targum; but he was slain not at Gob, but in the valley of Elah, nor had David any such name as Elhanan; he was one of David's worthies, 2 Samuel 23:24 ; where he is called the son of Dodo, and in 1 Chronicles 20:5 , the son of Jair; and Lahmi there may not be the name of Goliath's brother, but, as here, the country name of Elhanan; for the words F26 Vid. Buxtorf. Anticritic. par. 2. c. 2. p. 421. there may be rendered,"and Elhanan the son of Jair, the Lehemite (i.e. the Bethlehemite), slew the brother of Goliath the Gittite,'and so perfectly agrees, with this:

the staff of whose spear was like a weaver's beam ; not of Goliath's brother, but of Goliath himself, 1 Samuel 17:7 .
