Here we go again. For weeks now, we've been reading about the building of the tabernacle in the desert, the singular shrine to the one God. We've heard commandments for the manufacture of every piece of cloth, every golden joint and ladle, every bit of incense, every gem on the high priest's uniform. Now, in this week's reading, we are informed that the Israelites have carried out this project to the last letter, that they have donated to the effort their twenty-nine talents of gold, their hundred talents of silver, and countless other precious things—again in great detail.

Why does the biblical text, usually so sparse, dwell so lavishly and so long on this one project? A way of understanding these passages is to think about them as the literary finale of the book of Exodus.

We tend to speak of the Torah, the five books of Moses, as a single work divided into five parts, much like J.R.R.Tolkien's Lord of the Rings trilogy: one story made up of parts none of which can really stand alone. Yet Exodus is also its own book. Just as Genesis begins with the creation of the world and closes with the final words of the biblical patriarchs, Exodus, too, displays a demonstrable narrative arc, beginning with the oppression of the Israelites in Egypt and the birth of Moses, followed by the Hebrews' escape from slavery, their miraculous survival in the desert, the reception of the Ten Commandments.

And the creation of the tabernacle? In all of its detail, this episode powerfully marks not just the end but the completion, the summing-up, of the exodus from Egypt.  After the challenges posed to the Israelites' flight by Pharaoh's army, after all their own turmoil and infighting, after the hunger, the Golden Calf, the complaining, and the awe-filled moment of revelation, the Israelites laboriously prepare for—and achieve—a moment of order, of beauty, of repose, of unity of purpose, love of God, and reverence for Moses.

In brief, the tabernacle symbolizes the ultimate repudiation of Pharaoh's world, of both political and mental slavery. Now, it seems, a whole people has been enabled to live at last in the light of the one God, in the freedom of sovereign independence, in the truth of a morality higher than the whims of pagan gods and their earthly representatives.

Of course, as with all climactic moments in life, we cannot help being aware that this is a fleeting one. We know that the story is not over: that after the tabernacle there will be the continued drudgery of the desert, the failures encapsulated in the Sin of the Spies and the rebellion of Korah, the regressions to slave mentality. This is also, then, a moment that is decidedly mixed, a moment of celebration coupled with anticipation and even anxiety about what comes next.

But life itself is like that: a swelling motion from failure to success and back, a narrative that never really ends because every end is another beginning, every story a chapter in something longer and grander. As early as next week, the opening chapters of the book of Leviticus will vividly bring the point home as a strange and challenging new world of religious experience begins to unfold before our startled eyes.
