Ilai is a personal name appearing in the roster of David's mighty warriors. He is identified as an Ahohite, belonging to a Benjamite clan that produced several of David's elite fighters. The parallel passage in 2 Samuel 23:28 calls him Zalmon, suggesting either Ilai was his alternate name or a textual variant exists between the two accounts. David's mighty men were his most loyal and capable warriors, performing extraordinary feats of valor and forming the backbone of his military power. Ilai/Zalmon represents these heroes whose names were preserved in Israel's honor roll. The Ahohites contributed multiple warriors to David's forces, showing clan loyalty to the king.
