2 Maccabees 10:5–8

Now it so happened that the cleansing of the sanctuary took place on the very day on which it had been profaned by aliens, on the twenty-fifth day of the same month, which is Chislev. And they celebrated it for eight days with gladness like a feast of tabernacles, remembering how, not long before, during the feast of tabernacles they had been wandering like wild beasts in the mountains and the caves. So, bearing wands wreathed with leaves and fair boughs and palms, they offered hymns of praise to him who had prospered the cleansing of his own place, and also passed a public order and decree that all the Jewish nation should keep these ten days every year.
