Commentators observe that the people's unanimous promise was sincere but impulsive. John Calvin notes they were 'carried away by a kind of impulsive zeal and deceived themselves.' Other scholars point out that their vow, while well-intentioned, lacked a crucial element: an expressed dependence on God's grace to help them fulfill it. This serves as a powerful lesson on the difference between human enthusiasm and the Spirit-empowered perseverance needed for true obedience.
