You shall make no covenant with them and their gods. They shall not remain in your land, lest they cause you to sin against Me; for you will serve their gods - and it will prove a snare to you.
Consequently, these days are recalled and observed in every generation: by every family, every province, and every city. And these days of Purim shall never cease among the Jews, and the memory of them shall never perish among their descendants. – Esther 9:28
