'Appointed' in the Bible

Aaron will lay both his hands on the head of the live goat and confess over it all the Israelites’ wrongdoings and rebellious acts—all their sins. He is to put them on the goat’s head and send it away into the wilderness by the man appointed for the task.

For the life of a creature is in the blood, and I have appointed it to you to make atonement on the altar for your lives, since it is the lifeblood that makes atonement.

“Speak to the Israelites and tell them: These are My appointed times, the times of the Lord that you will proclaim as sacred assemblies.

“These are the Lord’s appointed times, the sacred assemblies you are to proclaim at their appointed times.

“These are the Lord’s appointed times that you are to proclaim as sacred assemblies for presenting fire offerings to the Lord, burnt offerings and grain offerings, sacrifices and drink offerings, each on its designated day.

So Moses declared the Lord’s appointed times to the Israelites.
