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.
