III Maccabees 6:32-41

32 Ceasing their miserable strain of woe, they took up the subject of their fatherland, hymning in praise God their wonder-working Saviour. All groans, all wailing, were laid aside: they formed dances in token of serene joy.
33 So, also, the king collected a number of guests for the occasion, and returned unceasing thanks with much magnificence for the unexpected deliverance afforded him.
34 Those who had marked them out as for death and for carrion, and had registered them with joy, howled aloud, and were clothed with shame, and had the fire of their rage ingloriously put out.
35 But the Jews, as we just said, instituted a dance, and then gave themselves up to feasting, glad thanksgivings, and psalms.
36 They made a public ordinance to commemorate these things for generations to come, as long as they should be sojourners. They thus established these days as days of mirth, not for the purpose of drinking or luxury, but because God had saved them.
37 They requested the king to send them back to their homes.
38 They were being enrolled from the twenty-fifth of Pachon to the fourth of Epiphi, a period of forty days: the measures taken for their destruction lasted from the fifth of Epiphi till the seventh, that is, three days.
39 The Ruler over all did during this time manifest forth his mercy gloriously, and did deliver them all together unharmed.
40 They feasted upon the king's provision up to the fourteenth day, and then asked to be sent away.
41 The king commended them, and wrote the subjoined letter, of magnanimous import for them, to the commanders of every city.
