The Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them, so as it should not fail, that they would keep these two days according to their writing, and according to their appointed time every year;

And the things that they suffered, and that were afterwards changed, the Jews took upon themselves and their seed, and upon all that had a mind to be joined to their religion, so that it should be lawful for none to pass these days without solemnity: which the writing testifieth, and certain times require, as the years continually succeed one another.

the Jews ordained and took upon them, and upon their seed, and upon all such as joined themselves to them, so that it should not fail, that they would observe these two days according to their writing and according to their fixed time, every year;

the Jews have established and received upon them, and upon their seed, and upon all those joined unto them, and it doth not pass away, to be keeping these two days according to their writing, and according to their season, in every year and year;

The Jews made a rule and gave an undertaking, causing their seed and all those who were joined to them to do the same, so that it might be in force for ever, that they would keep those two days, as ordered in the letter, at the fixed time every year;

The Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them, so as it should not fail, that they would keep these two (q) days according to their writing, and according to their [appointed] time every year;
(q) Meaning, the fourteenth and fifteenth days of the month of Adar.

The Jews ordained, and took upon them, and upon their seed, and upon all such that joined themselves unto them,.... Who became proselytes to their religion; that is, they appointed the above two days as festivals, and engaged for themselves, for their children, and all proselytes, to observe them as such; and one of their canons (s) runs thus,"all are obliged to read the Megillah (the book of Esther, which they always read on those days), priests, Levites, Nethinims, Israelites, men, women, and proselytes, and servants made free, and they train up little ones to read it:"
so as it should not fail; of being observed, so as no man should transgress it, or pass it over:
that they should keep these two days; the fourteenth and fifteenth of the month Adar or February:
according to their writing; in this book, the book of Esther, which was to be read, as Aben Ezra; written in the Hebrew character, as the Targum; that is, in the Assyrian character, as Jarchi; the square character, as they call it:
and according to their appointed time every year; whether simple or intercalated, as Aben Ezra observes: in an intercalary year the Jews have two Adars, and, though they keep the feast of Purim on the fourteenth of the first Adar, yet not with so much mirth, and call it the lesser Purim; but in the second Adar they observe it with all its ceremonies (t); so, in their canon, they do not keep Purim but in Adar that is next to Nisan or March, that redemption might be near redemption; the redemption of Mordecai near the redemption of Moses (u).

As joined - 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. According - According to that writing which was drawn up by Mordecai, and afterwards confirmed by the consent of the Jews.
