John Gill, on Esth 9:28

“These are the days which shall never be forgot: and which all provinces in the whole world shall celebrate throughout all generations: neither is there any city wherein the days of Phurim, that is, of lots, must not be observed by the Jews, and by their posterity, which is bound to these ceremonies.”

“And he sent letters unto all the Jews,.... That is, Mordecai did, signed in the queen's name, and his own: to the hundred twenty and seven provinces of the kingdom of Ahasuerus; among which was Judea, that was become a province, first of the Chaldean, now of the Persian empire, see Ezr 5:8 to whom also these letters were sent, directing and ordering the Jews there to observe these days, who were also concerned in the deliverance wrought: with words of peace and truth exhorting them to live in peace with one another, and their neighbours, and to constancy in the true religion; or wishing them all peace and prosperity in the most loving and sincere manner.”
