The Torah opens with Creation and describes the emergence of life and all things in just a single chapter. It spends the best part of two entire books detailing the Mishkan, with meticulous and exhaustive details of the planning, production, and assembly of the portable sanctuary that served as the physical and spiritual center of Judaism until the construction of a permanent Beis HaMikdash.
The Torah’s primary construction materials list contained vast amounts of gold, silver, copper, and precious gems. If you had to say the one main thing the Mishkan was made of, you might say gold, used throughout the project, from finishes to furnishings.
But it’s not.
The Mishkan had no foundation and no roof, just curtains and drapes. The only solid structure came from its walls, which were made of wood:
וְעָשִׂיתָ אֶת־הַקְּרָשִׁים לַמִּשְׁכָּן עֲצֵי שִׁטִּים עֹמְדִים – You shall make the planks for the Tabernacle of acacia wood, upright. (26:15)
The people contributed precious metals and gems they’d brought from Egypt. But they were in the desert; where were they getting wood from?
Rashi highlights that the Torah typically refers to everyday items and general contributions in other instances uses but in the case of wood, uses the definite article – the planks – indicating a specific contribution – הַקְּרָשִׁים / קְּרָשִׁים. Rashi notes that this wood had been designated generations before; our sages teach that before our ancestor Yakov went to Egypt, he visited his grandfather Avraham’s home, took some trees from there, and took them to Egypt with him, making his children swear at his deathbed to take the trees with them when they left to build a sanctuary with.
R’ Yaakov Kamenetsky notes that Yakov didn’t just plant trees; he planted actualized hope in a physical and visual form accessible in the external world of tangible things. Enslaved in Egypt, his descendants would look at and tend to their grandfather’s trees, a promise and symbol that the hands that built pyramids and monuments for their masters would one day make sacred things and places for themselves; work that broke and destroyed could transform into work that built and united.
Yaakov knew his children would raise their eyes and cry in misery. They’d see trees that connected them to the roots of their history and would allow them a glimpse of his hopeful vision of a better, brighter future.
But hope for the future isn’t necessarily specific to trees; Yakov could have left them anything.
He chose to leave trees because trees symbolize life and vitality, seasonality, and natural energy, representing the cycle of life and death. Like trees, generations of death in Egypt would burst to life once more.
Our great ancestors had a tangible vision for what these trees could become and took concrete action to imbue them with meaning so that this vision would unfold in reality. Yaakov was a visionary, but his dreams manifested in the world of action.
This is the wood they used, and it’s ubiquitous – the Mishkan is made of this wood, the Ark is made of this wood, the table is made of this wood, and the large and small altars are made of this wood, too. The wood may be overlaid with metal, but it’s all made of this wood.
More pointedly, wood is organic and simple, unlike gems and precious metals. R’ Zalman Sorotzkin points out in a way that’s hard to overstate that wood is the invisible support structure of no less than the entire project. You might see gold everywhere, but gold is just the decorative overlay; that’s not where the support comes from. Support comes from the durability and enduring sturdiness of the wood – עֲצֵי שִׁטִּים עֹמְדִים. The gold is useless without the underlying strength of the wood that holds it up.
Sparkle and glamor catch the eye, but remember, it’s superficial only.
The boards must be assembled upright, not upside down, in the direction of the tree’s original growth, with the lower part of the board corresponding to the lower part of the tree. Even though the board is symmetrical, this law extends to every mitzvah that uses plants, such as Lulav and Esrog. R’ Joseph Soloveitchik notes that this instruction is a universal law; the way to grow something is with its feet planted on the ground with its head, heart, and spine aligned straight up a straight line, physically, spiritually, and emotionally aligned. You can’t put something together upside-down and expect it to work right; things must be upright to grow correctly.
The Mishkan was built out of Yakov’s hopes and dreams for his children, the promise they inherited about the places they’d go and who they could be. Those children passed on that dream to their children, who would build the Mishkan, but also to us, the children who would remember it.
Every breath of our lives fulfills countless generations’ hopes and prayers. They aren’t burdens; they can be building blocks of lasting meaning if we use them right.
The dreams and promises we inherit are priceless treasures.
