39 "So, summing up: On the fifteenth day of the seventh month, after you have brought your crops in from your fields, celebrate the Feast of God for seven days. The first day is a complete rest and the eighth day is a complete rest. 40 On the first day, pick the best fruit from the best trees; take fronds of palm trees and branches of leafy trees and from willows by the brook and celebrate in the presence of your God for seven days - 41 yes, for seven full days celebrate it as a festival to God. Every year from now on, celebrate it in the seventh month. 42 Live in booths for seven days - every son and daughter of Israel is to move into booths 43 so that your descendants will know that I made the People of Israel live in booths when I brought them out of the land of Egypt. I am God, 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.
