'Ordained' in the Bible

Now I am building a temple for the name of Yahweh my God in order to dedicate it to Him for burning fragrant incense before Him, for displaying the rows of the bread of the Presence continuously, and for sacrificing burnt offerings for the morning and the evening, the Sabbaths and the New Moons, and the appointed festivals of the Lord our God. This is ordained for Israel forever.

Then Jehoiada put the oversight of the Lord’s temple into the hands of the Levitical priests, whom David had appointed over the Lord’s temple, to offer burnt offerings to the Lord as it is written in the law of Moses, with rejoicing and song ordained by David.
