Eluzai (אֶלְעוּזַי) combines El (God) and uz (strength, refuge). The meaning is "God is my strength" or "God is my refuge." The name appears in 1 Chronicles 12:5 as one of the Benjaminite warriors who defected to David at Ziklag — ambidextrous archers willing to risk everything to join God's anointed king.
Eluzai's name declares the theological foundation of his military service: God is the ultimate source of strength. This Benjaminite — from Saul's own tribe — chose David over Saul, recognizing that God's anointing was the true source of power. This mirrors the Christian's posture: we serve God's anointed King (Christ) not in our own strength but because El is our uzzi — our strength and refuge (Psalm 28:7). Paul echoes this in Philippians 4:13: "I can do all this through him who gives me strength."
