לה'. שהזכיר השם והנדר אם יהיה כן אתן לשם כך וכך או אתענה: UNTO THE LORD. He mentions God’s name. He vows as follows: If this comes to pass, then I will give the following sum to God, or I will fast.
השבע. שם הפועל ובא עם שם וכמוהו רבים: SWEARETH. Hishavah (sweareth) is an infinitive. It is connected to a noun.10When an infinitive is connected to a word, that word is usually a verb. Compare, ve-rappo yerrape (and shall cause him to be thoroughly healed) (Ex. 21:19). Hence I.E.’s comment. There are many such cases.11Compare, shefot ha-shofetim (when the judges judged) (Ruth 1:1).
לא יחל דברו. כמו לא יחלל ואיננו לשון מחילה והנה אנחנו צריכין לקבלה כי הכ' אמר איש ואשה ולא פירש מתי יהיה איש או מתי תהיה אשה: HE SHALL NOT BREAK HIS WORD. Lo yahel (he shall not break) means he shall not profane. The word yahel is not related to the word mechilah (forgiveness). We need tradition,12To ascertain the age at which one is obligated to keep one’s vows. for Scripture speaks of a man and a women but does not tell us at what age a person is considered a man or at what age a female is considered a women.13And is obligated to keep his or her vows.
