(42) Dwell in booths seven days.--Because the eighth day was a separate festival, when the booths were no more used. (See Leviticus 23:36.)

23:33-44 In the feast of Tabernacles there was a remembrance of their dwelling in tents, or booths, in the wilderness, as well as their fathers dwelling in tents in Canaan; to remind them of their origin and their deliverance. Christ's tabernacling on earth in human nature, might also be prefigured. And it represents the believer's life on earth: a stranger and pilgrim here below, his home and heart are above with his Saviour. They would the more value the comforts and conveniences of their own houses, when they had been seven days dwelling in the booths. It is good for those who have ease and plenty, sometimes to learn what it is to endure hardness. The joy of harvest ought to be improved for the furtherance of our joy in God. The earth is the Lord's, and the fullness thereof; therefore whatever we have the comfort of, he must have the glory of, especially when any mercy is perfected. God appointed these feasts, Beside the sabbaths and your free-will offerings. Calls to extraordinary services will not excuse from constant and stated ones.Ye shall dwell in booths seven days,.... So that it seems they were not obliged to dwell in them on the eighth day, which was an holy convocation, a sabbath in which no servile work was to be done as the first, Leviticus 23:36. The eighth day was a day by itself, a sort of an appendage to the feast of tabernacles, when they went into their houses again, and kept it as an holy day; and perhaps principally in giving thanks for the ingathering of the fruits of the earth, to which this seems to be appropriated from Leviticus 23:39. According to the Jewish writers, they did not go out of their booths until they had dined in them on this day; and as they went out used to say,"may it be the will of God that we may be worthy the next year to dwell in the booth of Leviathan (c);''that is, to feast with the Messiah in the world to come. And to those days the Jews have added a ninth, which they call "the joy of the law", and which they keep for joy of having finished the reading of the law; which being divided into as many sections or lessons as weeks in the year, were so ordered to be read as to be finished at this time (d):

all that are Israelites born shall dwell in booths; the Targum of Jonathan is,"all the males in Israel, and even the little ones, that do not need their mothers, sit in the shades blessing their Creator, when they enter there.''And, according to the Misnah (e), women, servants, and little ones, are free from the booths (i.e. are not obliged to dwelt in one), but a little one, who hath no need of its mother, is obliged to dwell in the booths: and elsewhere it is said, that sick persons, and such as wait upon them, are not obliged, nor messengers upon any business, nor travellers and watchmen in cities, and keepers of gardens and orchards; if such travel, or keep watch in the day, they are obliged to be in them at night, and if in the night, then they are to dwell in them in the day (f). Jarchi says, that everyone born in Israel comprehends proselytes, who were bound by this law.
