2 Maccabees 10:6-8

Revised Standard Version Catholic Edition

⁶ And they celebrated it for eight days with rejoicing, in the manner of the feast of booths, remembering how not long before, during the feast of booths, they had been wandering in the mountains and caves like wild animals. ⁷ Therefore bearing ivy-wreathed wands and beautiful branches and also fronds of palm, they offered hymns of thanksgiving to him who had given success to the purifying of his own holy place. ⁸ They decreed by public ordinance and vote that the whole nation of the Jews should observe these days every year.
