'Fixed' in the Bible

They celebrated the Feast of Booths, as it is written, and offered the fixed number of burnt offerings daily, according to the ordinance, as each day required;

and afterward there was a continual burnt offering, also for the new moons and for all the fixed festivals of the Lord that were consecrated, and from everyone who offered a freewill offering to the Lord.

And I have given orders that if anyone makes any change in this word, one of the supports is to be pulled out of his house, and he is to be lifted up and fixed to it; and his house is to be made waste for this;

So now let our rulers be representatives for all the people, and let all those in our towns who are married to strange women come at fixed times, and with them the responsible men and the judges of every town, till the burning wrath of our God is turned away from us, and this has been done.
