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.

14 And thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy bondman, and thy handmaid, and the Levite, and the stranger, and the fatherless, and the widow, that are in thy gates.

15 Seven days shalt thou hold a feast to Jehovah thy God in the place which Jehovah will choose; for Jehovah thy God will bless thee in all thy produce, and in all the work of thy hands, and thou shalt be wholly joyful.

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

17 each [shall give] according to that which is in his power to give, according to the blessing of Jehovah thy God which he hath given thee.
