Esther 9:31ESV·author unknown

that these days of Purim should be observed at their appointed seasons, as Mordecai the Jew and Queen Esther obligated them, and as they had obligated themselves and their offspring, with regard to their fasts and their lamenting.

Matthew Henry Presbyterian @wholebiblehenry

We may well imagine how much affected Mordecai and Esther were with the triumphs of the Jews over their enemies, and how they saw the issue of that decisive day with a satisfaction proportionable to the care and concern with which they expected it. How were their hearts enlarged with joy in God and his salvation, and what new songs of praise were put into their mouths!

THE TWO DAYS OF PURIM MADE FESTIVAL. (Est 9:20-32) Mordecai wrote these things--Commentators are not agreed what is particularly meant by "these things"; whether the letters following, or an account of these marvellous events to be preserved in the families of the Jewish people, and transmitted from one generation to another.

Geneva Bible Notes Reformed @genevanotes

To confirm these days of Purim in their times [appointed], according as Mordecai the Jew and Esther the queen had enjoined them, and as they had decreed for themselves and for their seed, the matters of the fastings and their cry. (s) That they would observe this feast with fasting and earnest prayer, which in Hebrew is signified by this word (they cry).
