Deuteronomy 16:15 Meaning and Commentary

Deuteronomy 16:15

Seven days shalt thou keep a solemn feast unto the Lord thy
God
The feast of tabernacles still spoken of:

in the place which the Lord thy God shall choose:
the city of Jerusalem:

because the Lord thy God shall bless thee in all thy increase, and in
all the works of thine hands;
both in the increase of their fields, vineyards, and oliveyards, and also in their several handicraft trades and occupations they were employed in; so Aben Ezra interprets all the works of their hands of merchandise and manufactories:

therefore thou shalt surely rejoice;
extremely, heartily, and sincerely, and not fail to express joy on this occasion, and manifest it by a generous freewill offering to the Lord, and a bountiful entertainment for himself, his family, friends, and others.

Deuteronomy 16:15 In-Context

13 After you have gathered the grain from your threshing floor and made your wine, celebrate the Festival of Booths for seven days.

14 Enjoy yourselves at the festival along with your sons, daughters, male and female slaves, the Levites, foreigners, orphans, and widows who live in your cities.

15 For seven days you will celebrate this festival dedicated to the LORD your God in the place he will choose. You will enjoy yourselves, because the LORD your God will bless all your harvest and all your work.

16 Three times a year all your men must come into the presence of the LORD your God at the place he will choose: at the Festival of Unleavened Bread, the Festival of Weeks, and the Festival of Booths. But no one may come into the presence of the LORD without an offering.

17 Each man must bring a gift in proportion to the blessings the LORD your God has given him.
