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 you shall rejoice in your feast, you, and your son, and your daughter, and your man-servant, and your maid-servant, and the Levite, and the sojourner, and the fatherless, and the widow, who are within your gates.

15 Seven days shall you keep a feast to Yahweh your God in the place which Yahweh shall choose; because Yahweh your God will bless you in all your increase, and in all the work of your hands, and you shall be altogether joyful.

16 Three times in a year shall all your males appear before Yahweh your 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 tents; and they shall not appear before Yahweh empty:

17 every man shall give as he is able, according to the blessing of Yahweh your God which he has given you.
