Esther 9:24–28

²⁴For Aman, the son of Amadathi of the race of Agag, the enemy and adversary of the Jews, had devised evil against them, to kill them and destroy them; and had cast Phur, that is, the lot.

²⁵And afterwards Esther went in to the king, beseeching him that his endeavours might be made void by the king’s letters: and the evil that he had intended against the Jews, might return upon his own head. And so both he and his sons were hanged upon gibbets.

²⁶And since that time these days are called Phurim, that is, of lots: because Phur, that is, the lot, was cast into the urn. And all things that were done, are contained in the volume of this epistle, that is, of this book:

²⁷And 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.

²⁸These are the days which shall never be forgot: and which all provinces in the whole world shall celebrate throughout all generations: neither is there any city wherein the days of Phurim, that is, of lots, must not be observed by the Jews, and by their posterity, which is bound to these ceremonies.
