It shall be a statute for ever in your generations: ye shall celebrate it in the seventh month.23 :42 Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths: 23:43 That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the LORD your God.23:44 And Moses declared unto the children of Israel the feasts of the LORD. In verses, one to 44, All the ceremonial laws, that is the animal sacrifices, Aaron’s priesthood and all the utensils had been separated from the words of God or had been nailed to the cross. God commanded Moses to tell the children of Israel about His feasts: The Israelites did not own the feasts of God. All the words of God concerning His feasts have been separated from the dross of the ceremonial laws by the blood of Jesus Christ to be observed in the new covenant which is the blood of Jesus Christ in Spirit and truth.
Leviticus 2323 :1 And the LORD spake unto Moses, saying, 23:2 Speak unto the children of Israel, and say unto them, Concerning the feasts of the LORD, which ye shall proclaim to be holy convocations, even these are my feasts
Concerning God’s new year in Exodus 12 &13
Exodus 12
1 And the LORD spake unto Moses and Aaron in the land of Egypt saying, 12:2 This month shall be unto you the beginning of months: it shall be the first month of the year to you.
Exodus 13
4 This day came ye out in the month Abib.13:5 And it shall be when the LORD shall bring thee into the land of the Canaanites, and the Hittites, and the Amorites, and the Hivites, and the Jebusites, which he sware unto thy fathers to give thee, a land flowing with milk and honey, that thou shalt keep this service in this month. One can see that in all these God commanded Moses to tell the children of Israel and God never attributed His feast days to the Israelites and the words of God are God Himself John 1:1.The conclusion of the whole thing is that all the feasts of God needs to be observed without the ceremonial laws which Jesus Christ nailed to the cross but not the feasts of God which are God’s words John 1:1. All the spoken words of God concerning His feasts cannot be washed away, but they were separated from the dross of the ceremonial laws. The words of God are permanent and will always perform their tasks.
