It's one of longest running religious colonies in the United States and it's located in southwest Michigan.

At its peak in the early 1900s, the House of David in Benton Harbor had 1,000 members and was a multi-million dollar business empire.

Today, over 100 years later, the colony is still in existence, and its believers are preparing for what they describe as the New Millenium.

“This is my grandfather here. He was the operator of the shop,” says Ron Taylor pointing to a man with long hair in a black and white photo on display at Mary's City of David Museum.
Taylor is proud to have followed in his grandfather’s footsteps, not only in the way he looks, (his beard is more than three feet long. He braids it and pins it up under his chin), but what he believes.
“That Christ is coming to establish his kingdom on Earth,” says Taylor, who at  65 is the youngest and one of the few remaining members of “Mary’s City of David,” an offshoot of the House of David, one of the most fascinating third longest lasting religious communes in America.
“We live collectively. We share out of the same pot. Everybody is given their needs daily, clothing, shelter, food, medical attention. And we’ve done that very responsibly for over 100 years here,” says Taylor.
The Israelite House of David was founded in 1903 in Benton Harbor by Benjamin Purnell and his wife Mary.
Purnell, a traveling preacher from the hills of Kentucky, proclaimed he received a message from God and was the 7th messenger as prophesied in the Book of Revelations.
The House of David followers are Christian millenialists, believing there will be an “Ingathering” of the scattered tribes of Israel and that Christ will return to earth for his 2nd coming and reign for 1,000 years.
As membership grew from 7 to over 700 in 1908, the highly skilled believers constructed massive elaborate buildings named Bethlehem, Jerusalem and Shiloh to live in along Britain Avenue in Benton Harbor. 
There are two beliefs about why the Purnells started the colony there. One is the Purnells said they received a "holy vision" that the colony should be built there. The other more practical reason is the fact the Purnells were friends with the promient Baushke family in Benton Harbor and they were able to bankroll the start of the colony there.
