Overview
Lahmi was a Philistine giant and brother of the famous Goliath. He was killed by Elhanan son of Jair during one of the conflicts between Israel and the Philistines in the time of King David. His defeat exemplifies how God gave Israel victory over their enemies through various warriors, not just through David alone.
