When God took our forefathers out of Egypt, He performed innumerable miracles for them – the Ten Plagues, the Giving of the Torah, the Man, the quails, the Well.
Yet the Tabernacle of the Lord did not corner down in fire from the heavens, but was built from the contributions of each and every Israelite.
Eliezer the Great speaks of the time prior to the corning of Mashiach when he says:
We do not know how the Temple will be built, but it is we, each and every one of us, who must contribute its foundations.
Everyone will give his stone, his small share.
Two stones build two houses; three stones build six houses (Sefer Yetzirah), and so on, ad infinitum.
When these stones corner together, The City of our God will be built.
And then, only then, will we be able to say that we do indeed have someone on whom we can rely – Our Father in Heaven.
–Rabbi Adin Steinsaltz
