And the explanation for this is as we find in Parashat Vayelech (Deuteronomy 31). 2 purify yourselves. that you should wash your body 3 and change your clothes.

In Beit El Jacob fulfilled his vow and gave a tenth of his wealth to honor God so that a person living in that generation could see fit to learn a lesson.
