The Jews took upon them and upon their seed To the latest generations; and upon all such as joined themselves unto them That is, the Gentile proselytes, who were obliged to submit to other of the Jewish laws, and therefore to this also; the rather, because they enjoyed the benefit of this day's deliverance, without which the Jewish nation and religion had been in a great measure, if not wholly, extinct in the world. That they would keep these two days according to their writing According to that writing which was drawn up by Mordecai with Esther's consent, (Esther 9:23; Esther 9:29,) and afterward confirmed by the consent of all the Jews in the several places. So that the observation of this feast was to be both universal and perpetual: even the proselytes were to observe it, in token of their sincere affection to the Jewish nation, and their having interests twisted with theirs. A concurrence in joys and praises is one branch of the communion of saints.
