quoted from "SALVATION" book 1939
[type under picture of beth sarim]
At san Diego, California, there is a small piece of land, on which, in the year 1929, there was built a house, which is called and known as Beth-Sarim. The Hebrew words Beth Sarim mean "House of the Princes" and the purpose of acquiring that property and building the house was that there might be some tangible proof that there are those on earth today who fully believe God and Christ Jesus and in His kingdom, and who believe that the faithful men of old will soon be resurrected by the Lord, be back on earth, and take charge of the visible affairs of earth...it was thought well and pleasing to God that the aforementioned house be built as a testimony to the name of Jehovah and showing faith in his announced purposes. The house has served as a testimony to many persons throughout the earth, and while the unbelievers have mocked concerning it and spoken contemptuously of it, yet it stands there as a testimony to Jehovah's name;...Salvation, p. 311
....those faithful men of old may be expected back from the dead any day now. The Scriptures give good reason to believe that it shall be shortly before Armageddon breaks.
In this expectation the house at San Diego, California, which house has been much publicized with malicious intent by the religious enemy, ...It is now held in trust for the occupancy of those princes on their return......(The new World), p104

Briefly it may be said that Brother Rutherford had a severe case of pneumonia after his release from unjust imprisonment during 1918-1919 because of his faithfulness to Jehovah.....(too sick to stay in brooklyn)
In time, a direct contribution was made for the purpose of constructing a house in San Diego for Brother Rutherford's use. It was not built at the expense of the Watch Tower Society. Concerning this property, the 1939 book Salvation stated: "At San Diego, California, there is a small piece of land, on which, in the year 1929, there was built a house, which is called and known as Beth-Sarim" [nuff said, don't need to include the rest of what the salvation book "proclaimed"]
Here in this book "Millions Now Living Will Never Die" pg 89, Rutherford predicted Abraham Isaac and Jacom would return to earth in 1925, he states that they would not be going to heaven, but would be on earth..
EARTHLY RULERS
..These can never be a part of the heavenly class; they had no heavenly hopes; but God has in store something good for them. They are to be resurrected as perfect men and constitute the PRINCES or rulers in the earth, according to his promise. (Psalm 45:16; Isaiah 32:1; Matthew 8:11) Therefore we may confidently expect that 1925 will mark the return of Abraham,.....
Here is Matt 8:11 NWT
But I tell YOU that many from eastern parts and western parts will come and recline at the table with Abraham and Isaac and Jacob in the kingdom of the heavens; whereas the sons of the kingdom will be thrown into the darkness outside. There is where [their] weeping and the gnash.....
In their own bible, we see that they will be in heaven: as this is where the table is located, and they are seated at it.
Just thought I'd add some history to these princes.
