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 Thou shalt keep the feast of tabernacles seven days, after that thou hast gathered in from thy threshing-floor and from thy winepress:

14 and thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy man-servant, and thy maid-servant, and the Levite, and the sojourner, and the fatherless, and the widow, that are within thy gates.

15 Seven days shalt thou keep a feast unto Jehovah thy God in the place which Jehovah shall choose; because Jehovah thy God will bless thee in all thine increase, and in all the work of thy hands, and thou shalt be altogether joyful.

16 Three times in a year shall all thy males appear before Jehovah thy God in the place which he shall choose: in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles; and they shall not appear before Jehovah empty:

17 every man shall give as he is able, according to the blessing of Jehovah thy God which he hath given thee.
