🔼The name Lahmi in the Bible
Roughly half a century after young David plinked Goliath of Gath, the army of now king David found itself at war with the Philistines. Elhanan, son of Jair of Bethlehem, took on Lahmi, the brother of Goliath, whose spear shaft was like a weaver's beam, and killed him (1 Chronicles 20:5).
🔼Etymology of the name Lahmi
The name Lahmi comes from either of the two roots לחם (laham), meaning either to eat (bread) or to wage war:
The letter י (yod) upon which our name ends, may either create an adjective (Bellicose or Edible), a possessive form (My Battle or My Food).
For a meaning of the name Lahmi, NOBSE Study Bible Name List sees the yod as the mark of the adjective, turns the name into an ethnonym and frustratingly translates our name as Bethlehemite. This is obviously quite daft since Lahmi was from Gath and the man who killed him was from Bethlehem.
Jones' Dictionary of Old Testament Proper Names also goes with the adjective and translates Lahmi as A Warrior or An Eater. BDB Theological Dictionary doesn't translate our name but does list it under the verb לחם II (laham II), meaning to eat.
