And whatever they suffered, and whatever was altered afterwards, the Jews received for themselves and their offspring and for all who were willing to be joined to their religion, so that none would be permitted to transgress the solemnity of these two days, to which the writing testifies, and which certain times require, as the years continually succeed one another
