When describing the material and process of creating the mishkan (tabernacle), G-d instructs us to “make the planks of acacia wood, upright” (26:15). Why does G-d specify the type of wood to use, and what does the term “upright” add?

While the Gemara (Sukkah 45) explains that planks of the acacia tree will last forever, the Ktav Sofer adds a deeper understanding of the particular species used. The acacia tree does not bear fruit, nor is it a particularly tall or beautiful tree. The acacia’s best quality is its sturdiness and dependability, key ingredients for creating a home, upright. These qualities enable the acacia tree and the structures created with its wood to endure the test of time. What has staying power in our lives is not the flash or grandeur, but stability and reliability.
