'Fixed' in the Bible

So the king summoned Jehoiada the chief priest and said to him, “Why have you not required the Levites to bring in from Judah and from Jerusalem the levy fixed by Moses the servant of the Lord on the congregation of Israel for the tent of the testimony?”

They made a proclamation in Judah and Jerusalem to bring to the Lord the levy fixed by Moses the servant of God on Israel in the wilderness.

He also appointed the king’s portion of his goods for the burnt offerings, namely, for the morning and evening burnt offerings, and the burnt offerings for the sabbaths and for the new moons and for the fixed festivals, as it is written in the law of the Lord.
