'Fixed' in the Bible

There were fair hangings of white and green and blue, fixed with cords of purple and the best linen to silver rings and pillars of polished stone: the seats were of gold and silver on a floor of red and white and yellow and black stone.

The Jews made a rule and gave an undertaking, causing their seed and all those who were joined to them to do the same, so that it might be in force for ever, that they would keep those two days, as ordered in the letter, at the fixed time every year;

Giving the force of law to these days of Purim at their fixed times, as they had been ordered by Mordecai the Jew and Esther the queen, and in keeping with the rules they had made for themselves and their seed, in connection with their time of going without food and their cry for help.
