כִּֽי־תִדֹּ֥ר נֶ֙דֶר֙ לַיהוָ֣ה אֱלֹהֶ֔יךָ לֹ֥א תְאַחֵ֖ר לְשַׁלְּמ֑וֹ כִּֽי־דָּרֹ֨שׁ יִדְרְשֶׁ֜נּוּ יְהוָ֤ה אֱלֹהֶ֙יךָ֙ מֵֽעִמָּ֔ךְ וְהָיָ֥ה בְךָ֖ חֵֽטְא׃
Quand tu auras fait un vœu à l’Éternel, ton Dieu, ne tarde point à l’accomplir; autrement, l’Éternel, ton Dieu, ne manquerait pas de t’en demander compte, et tu aurais à répondre d’un péché.
Tosefta Rosh Hashanah
How so, "for [pilgrimage] festivals"? One who vows, one who valuates himself [by donating his value to the Temple], and one who consecrates his property, does not transgress the law of "do not delay" (Deut. 23:22) until all the festivals of a year have passed him by. Rabbi Shimon says, three festivals according to their order, and Festival of Matzah is first. And so too would Rabbi Shimon say, sometimes they are three and sometimes they are four, and sometimes they are five. How so? One who vows before Passover, [he has not transgressed the law of "do not delay"] until Passover, Shavuot, and Sukkot pass him by. [If he vows] before Shavuot, [he has not transgressed] until Shavuot and Sukkot [of the current year], and Passover, and Shavuot, and Sukkot [of the next year] pass him by. [If he vows] before Sukkot, [he has not transgressed] until Sukkot [of the current year], and Passover, and Shavuot, and Sukkot [of the next year] pass him by.
