Numbers 28

Daily offerings, a lamb from each Israelite in the morning and another in the evening along with grain and drink offerings in the morning and evening. Those were some busy priests. Evidently the Israelites had an abundance of sheep.

Sabbath offerings, an additional two lambs, four lambs altogether for each Israelite. So, did the priests not get a day of rest? Did they rotate so that each got a day off even if it wasn't always the Sabbath?

Monthly offerings, a very busy day at the start of each month ... especially if it fell on a Sabbath. In addition to the other regular offerings ... two bulls, 1 ram, 7 lambs, 1 goat and accompanying grain and drink offerings.

Passover and Feast of Weeks, no regular work done just lots and lots of offerings.
