Ibn Ezra on Deuteronomy 23:24/אבן עזרא על דברים כ״ג:כ״ד

אמוצא שפתיך. בכל דבר שיש בו זכר לשם:
1THAT WHICH IS GONE OUT OF THY LIPS. Regarding anything where God’s name is mentioned.78
בנדבה. כי כל נדר נדבה ואין כל נדבה נדר וזה הדבר ברור:
2FREELY.79. The reference is to an offering which is freely given. For every vow offering80. is a free-will offering.81 (freely). According to I.E. comments on Lev. 7:15 a neder refers to a vow made in a time of stress, a nedavah refers to an offering brought whenever the spirit moves a person to do so. For the talmudic point of view see Megillah 1:6. However, not every free-will offering is a vow offering.82 The aforementioned is clear.83
גאשר דברת בפיך. אחר שיצא הדבור לא תוכל להשיבו:
3WHICH THOU HAST PROMISED WITH THY MOUTH. After the vow has come out of your mouth you cannot take it back.
