Shared ground
Esther 3:7 slows the story down to fix Haman’s plan on a calendar. The text explicitly says the casting happens in Nisan (month 1) in the twelfth year of Ahasuerus, and that the outcome points to Adar (month 12). This creates a long lead time between the decision and what Haman intends to do next.
The verse also explicitly explains a foreign word: “Pur” means “lot.” Whatever else is going on, the narrative presents Haman’s plan as being timed by a lot-casting process carried out “before Haman,” tying the result to his oversight and intentions.
Where interpretation differs
A main uncertainty is who “they” are. The verse does not identify the lot-casters. Some read it as Haman’s advisors or court officials acting under his direction; others think it points to specialists (such as diviners) who would be consulted for choosing an auspicious time.
A second uncertainty is how the selection worked. The line “from day to day, and from month to month” could suggest repeated casting until a final month/day was indicated, or a more ordered procedure that surveyed options across the calendar.
A third uncertainty is what “before Haman” emphasizes: his physical presence (he watches it happen) or his authority (it is done under his supervision).
Why the disagreement exists
The verse is dense and procedural, but it does not describe the method (how many casts, how results were read, who performed it). The wording “day to day” and “month to month” is also brief enough to allow more than one reasonable reconstruction of the process.
What this passage clearly contributes
This verse contributes a clear narrative point: Haman’s destructive plan is not impulsive; it is scheduled and calculated, and it ends up set far in advance (from Nisan to Adar). It also introduces “Pur” as a key term inside the story’s world—an act of date-setting by lots that will matter for how later events are remembered (compare Esther 9:24).
