-first grain wave offering was to be offering on the day AFTER the Sabbath.
-on that day a lamb must be sacrificed.
-from that day (which is AFTER the Sabbath) count off 50 days up to the 7th Sabbath, then offer new grain to the Lord. (I think this is a picture of Pentecost).

-seven lambs, a young bull and two rams as a burnt offering.
-also one goat and two lambs as a sin offering.
-on that day hold a sacred assembly and do no work.

Day of Atonement
-on the 10th day of the 7th month.

-deny yourself (fast begins on the evening of the 9th day until the evening of the 10th day).

LORD'S Feast of Tabernacles
-15th till the 22nd day of the 7th month.
-on the first day (the 15th) hold a sacred assembly - also a day of rest.
-present offerings for seven days.
-take fruit and palm fronds and rejoice before the Lord for seven days.
-live in booths for seven days (as a reminder of when the Israelites lived in booths).
-on the eighth day hold a closing sacred assembly - also a day of rest.

God is big into getting his people to worship together, to take rest, to eat food and to throw parties. After the Day of Atonement the people are to celebrate for 7 days straight...no wonder - their sins where atoned for.
