39 'Only—in the fifteenth day of the seventh month, in your gathering the increase of the land, ye do keep the feast of Jehovah seven days; on the first day 'is' a sabbath, and on the eighth day a sabbath; 40 and ye have taken to yourselves on the first day the fruit of beautiful trees, branches of palms, and boughs of thick trees, and willows of a brook, and have rejoiced before Jehovah your God seven days. 41 'And ye have kept it a feast to Jehovah, seven days in a year—a statute age-during to your generations; in the seventh month ye keep it a feast. 42 'In booths ye dwell seven days; all who are natives in Israel dwell in booths, 43 so that your generations do know that in booths I caused the sons of Israel to dwell; in my bringing them out of the land of Egypt; I, Jehovah, 'am' your God.'
Matthew Henry's Commentary on Leviticus 23:39-43
Commentary on Leviticus 23:33-44
(Read Leviticus 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.
