One of the blessings of the Torah is that "I shall give My tabernacle in your midst..." (Leviticus 26:11). When Israel returns to the Torah as prophesied in Deuteronomy 30:1-10, and blessings of obedience are upon them, this will also come to pass. The tabernacle will be brought back into existence, and the ceremonies of the tabernacle will come with it.
The other references to the Tabernacle being an Eternal Commandment can be found in Exodus 27:20-21, Leviticus 16:32-34, Leviticus 24:2-4, Numbers 18:20-24, Numbers 18:31.
Either way, it is very clear from the Torah that the Tabernacle is considered a permanent dwelling of God and all holy service is concentrated around it. All Levitical rituals and service was centered around the Tabernacle and therefore it is our responsibility to uphold this commandment by rebuilding the Tabernacle speedily and in our days!
