'Appointment' in the Bible

And Jonadab, the son of Shimeah David's brother, answered and said, Let not my lord suppose that they have slain all the young men the king's sons; for Amnon only is dead; for by the appointment of Absalom this has been determined from the day that he humbled his sister Tamar.

And that which they have need of, both young bullocks and rams and lambs, for the burnt-offerings to the God of the heavens, wheat, salt, wine, and oil, according to the appointment of the priests that are at Jerusalem, let it be given them day by day without fail;

And three friends of Job heard of all this evil that was come upon him. And they came each one from his place: Eliphaz the Temanite, and Bildad the Shuhite, and Zophar the Naamathite; and they made an appointment together to come to condole with him and to comfort him.
