Deuteronomy 16:7-17

7Roast the lamb and eat it in the place the Lord your God chooses. Then you may go back to your tents the next morning.

8For the next six days you may not eat any bread made with yeast. On the seventh day proclaim another holy day in honor of the Lord your God, and no work may be done on that day.

9“Count off seven weeks from when you first begin to cut the grain at the time of harvest.

10Then celebrate the Festival of Harvest to honor the Lord your God. Bring him a voluntary offering in proportion to the blessings you have received from him.

11This is a time to celebrate before the Lord your God at the designated place of worship he will choose for his name to be honored. Celebrate with your sons and daughters, your male and female servants, the Levites from your towns, and the foreigners, orphans, and widows who live among you.

12Remember that you were once slaves in Egypt, so be careful to obey all these decrees.

13“You must observe the Festival of Shelters for seven days at the end of the harvest season, after the grain has been threshed and the grapes have been pressed.

14This festival will be a happy time of celebrating with your sons and daughters, your male and female servants, and the Levites, foreigners, orphans, and widows from your towns.

15For seven days you must celebrate this festival to honor the Lord your God at the place he chooses, for it is he who blesses you with bountiful harvests and gives you success in all your work. This festival will be a time of great joy for all.

16“Each year every man in Israel must celebrate these three festivals: the Festival of Unleavened Bread, the Festival of Harvest, and the Festival of Shelters. On each of these occasions, all men must appear before the Lord your God at the place he chooses, but they must not appear before the Lord without a gift for him.

17All must give as they are able, according to the blessings given to them by the Lord your God.
