Forever

In this week's haftorah ( Yeshaya 51:12-52:13) Hashem tells the Bnei Yisrael that He will console them. The Yalkut Shimoni says that Avrohom couldn't console them because he called the Bais HaMikdash "Har" a mountain, neither could Yitzchok because he called it a "Sadeh", and neither could Yaakov who called it a "Bayis", house.

Reb Yehonoson Eibshitz explains this enigmatic Medrash and says that Bnei Yisrael couldn't be consoled with a promise of the rebuilding of the Bais HaMikdash because they were afraid that eventually their aveiros would cause it to be destroyed just like the previous ones. Avrohom's consolation fortelling of the future rebuilding didn't satisfy them. Avrohom referred to the Bais HaMikdash as a mountain and the pasuk says in tehilim "Mi Yaaleh BeHar Hashem...Neki Kapayim...; Who can go onto the mountain of Hashem only people with innocent hands and hearts." In that case they knew the Bais HaMikdash would rise and fall on their purity, not a good thing for them to hear.

Yitzhchok called it a Sadeh, a field which is open to all, including the non-Jews, with whose help it was built, allowing them to stake a claim to it as well. It was this influence of theirs that allowed the Bais HaMikdash to ultimately fall into their murderous and destructive hands. Yaakov called it a house. To enter Hashem's house requires the utmost modesty and humbleness, a level that they were afraid they could not maintain.

Only when Hashem said, "Anochi, Anochi, Hu Minachemchem." Hashem whose building and handiwork survives forever with no preconditions, were the Bnei Yisreal finally consoled.
