To start out with, I think there are lots of reasons that you should go to the feast of tabernacles for example one reason is because you get off work and you get to go somewhere and relax and do thinks with your family. another reason is you get to see friends and family at church that you only get to see once or twice a year. also the bible says to keep the feast.

First off I would like to turn to

Leviticus 23:33 - 44 (NKJV) 33Then 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. 35On the first day there shall be a holy convocation. You shall do no customary work on it. 36For seven days you shall offer an offering made by fire to the Lord.now what does this mean? This means to sacrifice a animal to the lord. We do not do this because when jesus sacrifice his life it took the place of it. 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. theses 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 38besides 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. 40And you shall take for yourselves on the first day the fruit of beautiful trees, branches of palm trees, the boughs of leafy trees, and willows of the brook; and you shall rejoice before the Lord your God for seven days. 41You shall keep it as a feast to the Lord for seven days in the year. It shall be a statute forever in your generations. You shall celebrate it in the seventh month. 42You shall dwell in booths for seven days. All who are native Israelites shall dwell in booths, 43that your generations may know that I made the children of Israel dwell in booths when I brought them out of the land of Egypt: I am the Lord your God.’” 44So Moses declared to the children of Israel the feasts of the Lord.

deuteronomy 16:16 Three times a year all your males shall appear before the Lord your God in the place which He chooses: at the Feast of Unleavened Bread, at the Feast of Weeks, and at the Feast of Tabernacles; and they shall not appear before the Lord empty-handed. 17Every man shall give as he is able, according to the blessing of the Lord your God which He has given you.so every three season you should all ways have a offeringr

Zechariah 14:16 - 19 (NKJV) 16And it shall come to pass that everyone who is left of all the nations which came against Jerusalem shall go up from year to year to worship the King, the Lord of hosts, and to keep the Feast of Tabernacles. 17And it shall be that whichever of the families of the earth do not come up to Jerusalem to worship the King, the Lord of hosts, on them there will be no rain. 18If the family of Egypt will not come up and enter in, they shall have no rain; they shall receive the plague with which the Lord strikes the nations who do not come up to keep the Feast of Tabernacles. 19This shall be the punishment of Egypt and the punishment of all the nations that do not come up to keep the Feast of Tabernacles.so in the future if you dont keep the feast you wont get rain

Now I would also like to talk about somthing else clean and nucleon food. Please turn to Leviticus 11:1 - 23 (NKJV) 1Now the Lord spoke to Moses and Aaron, saying to them, 2“Speak to the children of Israel, saying, ‘These are the animals which you may eat among all the animals that are on the earth: 3Among the animals, whatever divides the hoof, having cloven hooves and chewing the cud—that you may eat. 4Nevertheless these you shall not eat among those that chew the cud or those that have cloven hooves: the camel, because it chews the cud but does not have cloven hooves, is unclean to you; 5the rock hyrax, because it chews the cud but does not have cloven hooves, is unclean to you; 6the hare, because it chews the cud but does not have cloven hooves, is unclean to you; 7and the swine, though it divides the hoof, having cloven hooves, yet does not chew the cud, is unclean to you. 8Their flesh you shall not eat, and their carcasses you shall not touch. They are unclean to you. 9‘These you may eat of all that are in the water: whatever in the water has fins and scales, whether in the seas or in the rivers—that you may eat. 10But all in the seas or in the rivers that do not have fins and scales, all that move in the water or any living thing which is in the water, they are an abomination to you. 11They shall be an abomination to you; you shall not eat their flesh, but you shall regard their carcasses as an abomination. 12Whatever in the water does not have fins or scales—that shall be an abomination to you. 13‘And these you shall regard as an abomination among the birds; they shall not be eaten, they are an abomination: the eagle, the vulture, the buzzard, 14the kite, and the falcon after its kind; 15every raven after its kind, 16the ostrich, the short-eared owl, the sea gull, and the hawk after its kind; 17the little owl, the fisher owl, and the screech owl; 18the white owl, the jackdaw, and the carrion vulture; 19the stork, the heron after its kind, the hoopoe, and the bat. 20‘All flying insects that creep on all fours shall be an abomination to you. 21Yet these you may eat of every flying insect that creeps on all fours: those which have jointed legs above their feet with which to leap on the earth. 22These you may eat: the locust after its kind, the destroying locust after its kind, the cricket after its kind, and the grasshopper after its kind. 23But all other flying insects which have four feet shall be an abomination to you. 24‘By these you shall become unclean; whoever touches the carcass of any of them shall be unclean until evening; 25whoever carries part of the carcass of any of them shall wash his clothes and be unclean until evening: 26The carcass of any animal which divides the foot, but is not cloven-hoofed or does not chew the cud, is unclean to you. Everyone who touches it shall be unclean. 27And whatever goes on its paws, among all kinds of animals that go on all fours, those are unclean to you. Whoever touches any such carcass shall be unclean until evening. 28Whoever carries any such carcass shall wash his clothes and be unclean until evening. It is unclean to you.
