'Themselves' in the Bible

A copy of the edict to be issued as law in each and every province was published to all the peoples, so that the Jews would be ready for this day to avenge themselves on their enemies.

Now in the twelfth month (that is, the month Adar), on the thirteenth day when the king’s command and edict were about to be executed, on the day when the enemies of the Jews hoped to gain the mastery over them, it was turned to the contrary so that the Jews themselves gained the mastery over those who hated them.

Now the rest of the Jews who were in the king’s provinces assembled, to defend their lives and rid themselves of their enemies, and kill 75,000 of those who hated them; but they did not lay their hands on the plunder.

because on those days the Jews rid themselves of their enemies, and it was a month which was turned for them from sorrow into gladness and from mourning into a holiday; that they should make them days of feasting and rejoicing and sending portions of food to one another and gifts to the poor.

the Jews established and made a custom for themselves and for their descendants and for all those who allied themselves with them, so that they would not fail to celebrate these two days according to their regulation and according to their appointed time annually.

to establish these days of Purim at their appointed times, just as Mordecai the Jew and Queen Esther had established for them, and just as they had established for themselves and for their descendants with instructions for their times of fasting and their lamentations.
