G‑d then gave the instructions for demarcating the Courtyard with netted hangings suspended from copper-plated wooden pillars. The hangings were anchored to the ground by copper stakes.
Infusing Divinity
וְכָל יִתְדֹת הֶחָצֵר נְחֹשֶׁת: (שמות כז:יט)
All the stakes of the Courtyard must be made of copper. Exodus 27:19

The stakes were hammered into the earth, indicating that the holiness of the Tabernacle actually penetrated the ground. By building the Tabernacle in the desert, and by “building” our personal, inner Tabernacles, we infuse Divinity even into those places that appear to be, like the ground, inanimate and lifeless.1
