Haman had letters written in the king’s name and sealed with the king’s ring to destroy, kill, and annihilate all Jews—young and old, women and children—on a single day (Esther 3:12–13). The decree was published to all peoples so they would be ready for that day (Esther 3:14).
Esther 3:12–14 shows Haman’s plan turning into an official empire-wide order. On a specific date in the first month, royal scribes draft letters exactly as Haman dictates, addressed to every level of provincial leadership, in each region’s own script and language. These verses sit inside the escalation of Haman’s hostility toward Mordecai into a threat against an entire people (Esther 3:7; Esther 3:8–11). The narrative shifts from persuasion at court to administrative execution: what was proposed to the king becomes written policy.
Esther 3:12–14 describes how Haman’s proposal becomes official state policy. The story slows down to show the machinery of empire: scribes are summoned on a specific date, documents are produced at scale, and the message is customized for each province and people by script and language.
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Esther 3:12-13, then read the surrounding section so the answer stays connected to the passage's flow.
12Then were the king`s scribes called in the first month, on the thirteenth day of it; and there was written according to all that Haman commanded to the king`s satraps, and to the governors who were over every province, and to the princes of every people, to every province according to the writing of it, and to every people after their language; in the name of king Ahasuerus was it written, and it was sealed with the king`s ring.
13Letters were sent by posts into all the king`s provinces, to destroy, to kill, and to cause to perish, all Jews, both young and old, little children and women, in one day, even on the thirteenth [day] of the twelfth month, which is the month Adar, and to take the spoil of them for a prey.
