'Ordained' in the Bible

Observe, I am about to build a house for the Name of the Lord my God, dedicated to Him, to burn fragrant incense [of sweet spices] before Him, to set out the showbread continually, and to offer burnt offerings morning and evening, on Sabbaths, New Moons, and on the festivals of the Lord our God, as ordained forever in Israel.

But the downfall of Ahaziah was ordained by God, in that he went to Joram (Jehoram). For when he arrived there he went out [as an ally] with Jehoram against Jehu the son of Nimshi, whom the Lord had anointed to destroy the house of Ahab.

Then Hezekiah gave the order to offer the burnt offering on the altar. And when the burnt offering began, the song to the Lord also began with the trumpets accompanied by the instruments of David, king of Israel.
