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 z 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.
