'Appointed' in the Bible

Then Esther called for Hathach, one of the king's eunuchs, whom he had appointed to attend her, and commanded him to go to Mordecai, to find out what this was, and why it was.

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;

to confirm these days of Purim in their appointed times, as Mordecai the Jew and Esther the queen had decreed, and as they had imposed upon themselves and their descendants, in the matter of the fastings and their cry.
