24 "Speak to the children of Israel, saying: 'In the seventh month, on the first day of the month, you shall have a sabbath-rest, a memorial of blowing of trumpets, a holy convocation. 25 You shall do no customary work on it; and you shall offer an offering made by fire to the Lord.' " 26 And the Lord spoke to Moses, saying: 27 "Also the tenth day of this seventh month shall be the Day of Atonement. It shall be a holy convocation for you; you shall afflict your souls, and offer an offering made by fire to the Lord. 28 And you shall do no work on that same day, for it is the Day of Atonement, to make atonement for you before the Lord your God. 29 For any person who is not afflicted in soul on that same day shall be cut off from his people. 30 And any person who does any work on that same day, that person I will destroy from among his people. 31 You shall do no manner of work; it shall be a statute forever throughout your generations in all your dwellings. 32 It shall be to you a sabbath of solemn rest, and you shall afflict your souls; on the ninth day of the month at evening, from evening to evening, you shall celebrate your sabbath."

33 Then the Lord spoke to Moses, saying, 34 "Speak to the children of Israel, saying: 'The fifteenth day of this seventh month shall be the Feast of Tabernacles for seven days to the Lord. 35 On the first day there shall be a holy convocation. You shall do no customary work on it. 36 For seven days you shall offer an offering made by fire to the Lord. On the eighth day you shall have a holy convocation, and you shall offer an offering made by fire to the Lord. It is a sacred assembly, and you shall do no customary work on it 37 These are the feasts of the Lord which you shall proclaim to be holy convocations, to offer an offering made by fire to the Lord, a burnt offering and a grain offering, a sacrifice and drink offerings, everything on its day-- 38 besides the Sabbaths of the Lord, besides your gifts, besides all your vows, and besides all your freewill offerings which you give to the Lord 39 'Also on the fifteenth day of the seventh month, when you have gathered in the fruit of the land, you shall keep the feast of the Lord for seven days; on the first day there shall be a sabbath-rest, and on the eighth day a sabbath-rest.

the blowing of trumpets represented the preaching of the gospel, by which men are called to repent of sin, and to accept the salvation of Christ, which was signified by the day of atonement. Also it invited to rejoice in God, and become strangers and pilgrims on earth, which was denoted by the feast of Tabernacles, observed in the same month. At the beginning of the year, they were called by this sound of trumpet to shake off spiritual drowsiness, to search and try their ways, and to amend them. The day of atonement was the ninth day after this; thus they were awakened to prepare for that day, by sincere and serious repentance, that it might indeed be to them a day of atonement. The humbling of our souls for sin, and the making our peace with God, is work that requires the whole man, and the closest application of mind. On that day God spake peace to his people, and to his saints; therefore they must lay aside all their wordly business, that they might the more clearly hear that voice of joy and gladness.

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.
