Hushai's argument hinges on the power of reputation. Commentator John Gill explains that Hushai is using psychological tactics, warning that if Absalom's army suffers even a small initial setback, the most courageous soldiers—those with hearts like lions—will 'melt' in fear. This is because 'all Israel' knows the legendary prowess of David and his men. It's a reminder that a long-standing reputation for strength and integrity can serve as a powerful defense.
