פָּשַׁ֙טְתִּי֙ אֶת־כֻּתָּנְתִּ֔י אֵיכָ֖כָה אֶלְבָּשֶׁ֑נָּה רָחַ֥צְתִּי אֶת־רַגְלַ֖י אֵיכָ֥כָה אֲטַנְּפֵֽם׃
我脫了衣裳，怎能再穿上呢？我洗了腳，怎能再弄髒呢？
Mesillat Yesharim
And they said: "A person should always be quick to do a Mitzvah. For due to Lot's older daughter preceding her sister by one night she merited preceding her by four generations" (Nazir 23b).
