Yaakov's vow as preparation for generations

במדרש וידר יעקב נדר ח"א מסורסת הפרשה וחד אמר אם יתקיים בי התנאים כו'.

In the Midrash on "And Yaakov vowed a vow": one opinion holds that the passage is in inverted order, and another says it means "if the conditions are fulfilled in me," etc.

The Sefas Emes brings the Midrash's two readings of Yaakov's vow — one that the verse is out of sequence, and one that Yaakov made his vow conditional on his own future conduct.

ובודאי הכל אמת כי יעקב אבינו רצה שמצד עצמו יתקיימו בו התנאים ומוכן היה לזו התפלה גם מקודם שהבטיחו.

And surely both are true, for Yaakov Avinu wished that the conditions be fulfilled in him through his own merit, and he was ready for this tefillah (prayer) even before Hashem promised him.

Both opinions are correct: Yaakov wanted his standing before Hashem to rest on his own effort, and he was prepared to daven this prayer even prior to receiving Hashem's assurance.

והגם כי כבר הבטיח לו הקב"ה.

And even though the Holy One, blessed be He, had already promised him —

Hashem had already guaranteed His protection to Yaakov.

הוא עשה את שלו.

He, for his part, did his own.

Despite the promise, Yaakov did not rely on it but contributed his own avodah through prayer.

וזה עצמו ענין אין מאוחר בתורה.

And this itself is the matter of "there is no 'earlier' or 'later' in the Torah."

The principle that the Torah is not strictly chronological reflects this very idea — Yaakov's vow belongs, in essence, before the promise, even though it appears after it.

ונתקבל הנדר כאלו הי' נודר מקודם.

And the vow was accepted as though he had vowed it beforehand.

Because Yaakov was inwardly ready to make the vow even earlier, Hashem received it as if it had preceded the promise.

ויובן עוד עפ"י מ"ש חז"ל נדר לאמר שיהיו נודרין בעת צרה.

And it may be further understood according to what Chazal said: "he vowed, saying" — that people should make vows in a time of distress.

Chazal derive from the wording "vowed, saying" that Yaakov was establishing a pattern: in times of trouble, a person should make a vow to Hashem.

שהי' נדר ותפלה זו הכנה לדורות.

For this vow and tefillah were a preparation for all generations.

Yaakov's vow was not for himself alone; it laid the groundwork for his descendants to turn to Hashem in their own moments of distress.

ולכן הגם שנתקבל תפלתו כענין שנאמר טרם יקראו ואני אענה עוד הם מדברים כו'.

Therefore, even though his prayer was already accepted — as in the matter of which it is said, "Before they call, I will answer; while they are yet speaking" (Yeshayahu 65:24) —

Yaakov's prayer was answered in advance, embodying the verse that Hashem responds even before one finishes calling out.

מ"מ גמר תפלתו בפועל כדי שיהי' נשאר לדורות להיות נודרין בעת צרה הגם כי הוא כבר יצא מן הצרה שכבר הבטיחו הקב"ה מ"מ נדר לאמר כו':

Nevertheless he completed his prayer in actual deed, so that it would remain for the generations to make vows in a time of distress — for even though he had already emerged from the distress, since the Holy One, blessed be He, had already promised him, still he "vowed, saying," etc.

Even though Yaakov was already secure, he carried his vow through to completion in practice, precisely so that it would endure as a model and merit for his children to call upon in their own times of trouble.

Summary: Though Hashem had already promised to protect Yaakov, Yaakov still completed his vow and tefillah through his own effort — both because true avodah must come from one's own side ("there is no earlier or later in the Torah"), and because his vow was meant to remain as a lasting preparation and merit for all generations to turn to Hashem in times of distress.
