And ye shall rejoice before the Lord your God
In the place chosen and fixed, where a temple would be built for him, and he would take up his residence; eating with joy and gladness that part of the offerings which belonged to them, keeping as it were a feast before the Lord, in token of gratitude for what they had received from him:
ye and your sons, and your daughters, and your menservants,
which explains what is meant by their household, ( Deuteronomy 12:7 ) wives are not mentioned, because it could not be thought they would eat and rejoice, or keep such a feast, without them, and therefore needless to name them:
and the Levite that is within your gates;
such also were to partake of this entertainment, who were useful in instructing their families in the knowledge of divine things, and serviceable to them on many accounts in the worship of God:
forasmuch as he hath no part nor inheritance with
in the division of the land, and so having nothing to manure and cultivate, was destitute of the fruits of the earth, and could make no improvement and increase of his substance, as they could.
