Sa unang buwan, ang buwan ng Nisan, sa ikalabindalawang taon ni Haring Ahasuero, naghagis sila ng pur, ibig sabihin ay palabunutan, sa harap ni Haman, araw-araw at buwan-buwan, hanggang sa ikalabindalawang buwan, ang buwan ng Adar.

the month of Spring is so called because it was during the Springtime that they left Egypt. The Dissenters have claimed that one may not perform the Paschal sacrifice until Spring-time. I have replied to their nonsense elsewhere [comment on Exodus 12: 2] (nevertheless, we must acknowledge that the court did examine whether or not Spring had arrived). Know that in the Hebrew language the months have no proper names. The names that appear in Scripture — like Nisan [Esther 3: 7], Sivan [Esther 8: 9], Kislev [Nehemiah 1: 1], Ṭevet [Esther 2: 16], and Adar [Esther 3: 7] — are all Aramaic. Consequently, Scripture had to tell us, “…this being the month of Nisan” [Esther 3: 7]. The only Hebrew terms that we find are the descriptive terms “Splendor” [I Kings 6: 1], “Mighty” [I Kings 8: 2], and “Wilt” [I Kings 6: 38]. The original rule was that the first month (the month from which the others are counted) was to be reckoned with the coming of the Spring — whether the previous year had twelve or thirteen months being of no concern. However, our ancestors, of blessed memory, added other considerations, in addition to the Spring [Sanhedrin 11b]; and all of their words are true.
Ibn Ezra
And to say of the Place ליום זה פור הפיל — "For this day He cast lots" is incorrect; for one who sets up lots does not know the outcome. And he ought to have fled from the phrase "he cast lots" since you can only find it in the context of an enemy (Esther 3:7). And what's more, after God removes the heaven and earth, how will He מציון ימלוך — reign from Zion? That's part of the earth!
Sforno
זאת הארץ אשר תפול לכם בנחלה; the word תפול is used to describe the manner in which lots are drawn, i.e. a die is cast, falls. You will each be assigned your ancestral heritage even before the end of the military campaign resulting in the land’s conquest. The expression נפל in connection with lots is found in Psalms 22,18 as well as in Esther 3,7.
The reason why the Torah the word זאת, which at first glance appears to be superfluous, is to tell us that anything conquered outside the boundaries which will now be described is not subject to division by lottery. We find this confirmed by the fact that Moses distributed the lands of Sichon and Og without resorting to any lottery. The reason for this is that those lands do not have the degree of sanctity which is integral to the “Holy Land.” Joshua confirmed this when (Joshua 22,19) he spoke of ואך אם טמאה ארץ אחוזתכם, “even if the land of your inheritance is unclean,” [Joshua denied the right of the two and a half tribes on the east bank to build an altar even if thereby they had meant to add sanctity to the soil they lived on, which was not holy or sacred by definition. Ed.] The major reason why this land could not be distributed by lottery was that the lottery reflected Divine decisions, and G’d would not mix in unless the land concerned was holy by itself.
