Reference: Lahmi
Hastings
The brother of Goliath the Gittite, slain by Elhanan the son of Jair (1Ch 20:5). There is a discrepancy between this passage and the parallel passage in 2Sa 21:19, where we read that 'Elhanan [wh. see] the Bethlehemite slew Goliath the Gittite.' If the text of Chronicles is the more correct, the designation Bethlehemite of Samuel is simply a corruption of the name Lahmi, but the converse might also be the case.
