'Fail' in the Bible

Then the king said to Haman, "Hurry and take the clothing and the horse, as you have said, and do this for Mordecai the Jew, who sits at the king's gate. Let nothing fail of all that you have spoken."

the Jews established, and imposed on themselves, and on their descendants, and on all those who joined themselves to them, so that it should not fail, that they would keep these two days according to what was written, and according to its appointed time, every year;

and that these days should be remembered and kept throughout every generation, every family, every province, and every city; and that these days of Purim should not fail from among the Jews, nor the memory of them perish from their seed.
