The Willing Heart and Whether a Vow Must Be Spoken Aloud

They raised an objection: "that which goes out of your lips" (Deuteronomy 23:24) -- I have here only one who uttered it with his lips; from where do I learn one who resolved in his heart? The verse teaches, "everyone whose heart is willing" (Exodus 35:5). That case is different, for it is written there, "everyone whose heart is willing." Then let us learn from it. We cannot, because the offering of priestly gifts and consecrated items are two verses that come as one, and two verses that come as one do not teach a general rule. And according to the one who holds that they do teach, what is there to say? These are ordinary produce and consecrated items, and ordinary produce cannot be learned from consecrated items. It was taught: The permitting of vows hovers in the air and has nothing on which to rest. It was taught: Rabbi Eliezer says they do have something on which to rest, as it is stated, "everyone whose heart is willing." But perhaps this comes to exclude the view of Shmuel, who said that one who resolved in his heart must utter it with his lips; it teaches us that he is bound even though he did not utter it.
