It may be added, that this concept is also alluded to in the name of "Beis Rabbeinu" in our generation:
"Rabbeinu" [our Rebbe] - His two names alluded to the Redemption: His first name - Yosef - "And it shall come to pass that on that day, the L-rd shall continue to apply [yoseef] His hand a second time to acquire the rest of His people that will remain from Assyria and Egypt, etc. and from the islands of the sea, etc, and He shall gather [Asaf] the lost of Israel and the scattered ones of Judah He shall gather from the four corners of the earth."
His second name - Yitzchak - refers to the laughter and rejoicing that will be complete in the future Redemption, and which will be completed through our righteous Moshiach. Thus it is written, "Then our mouths will be filled with laughter [S'chok]. It specifies 'then,' in the future, when they will say to Yitzchak (specifically), 'Because you are our father.'"
And Beis (Rabbeinu) [The House of our Rebbe] - its number is seven hundred seventy. The name by which "Beis Rabbeinu" is called by all Jews has been universally accepted to be this number, whether in Hebrew, Yiddish or English - "Seven Seventy."
So in regard to an established dwelling). This is particularly true in our case, when the number becomes the name of the house, as discussed below.
