The Hebrew Betach (also Betah) is a city name meaning "security" or "trust." It appears in 2 Samuel 8:8 as a city of Hadadezer that David conquered and from which he took great quantities of bronze for the temple. The name reflects the root batach (to trust, be secure).
Even a place name like Betach (security/trust) carries theological resonance in the David narrative. The spoils of Betach — bronze taken from a city named "security" — were used by Solomon to furnish God's temple (1 Kings 7:47; 2 Chronicles 4:17–18). True security is not found in fortified cities but in God alone. The transfer of Betach's bronze to the temple becomes a silent sermon: what humans trust for protection ultimately serves the glory of God.
