The construction of the copper altar included the creation of dedicated carrying poles, allowing the sacred structure to travel with the Israelites through the desert. Crafted from acacia wood and overlaid with copper, these poles served a practical function while also holding profound historical and spiritual significance [ביאור שטיינזלץ, פירושן של נשים]. The instructions for making them are delivered with an unusual repetition, elaborating on the poles rather than using a brief, direct description.
This extended phrasing points to deeper layers of meaning. One perspective suggests that the repetition serves as a prophetic hint toward a future miracle in the Holy Temple, where the carrying poles of the Ark of the Covenant would miraculously extend [רבנו בחיי]. Another approach finds conceptual depth in the repetition by comparing the Altar, which represents the power of serving God and prayer, to the Ark, which represents the power of Torah. Unlike other vessels, the poles of both the Altar and the Ark had to remain permanently in their rings, symbolizing that the Israelites must always carry these two spiritual forces with them. However, a key distinction exists between them. The power of Torah remains uniform and constant across all times and places, whereas the methods of serving God adapt to the needs of different generations, shifting from physical sacrifices to the service of prayer. The elongated language regarding the Altar's poles hints at the various ways the Israelites would carry their devotion and service to God throughout history [העמק דבר].
The specific choice to use acacia wood for these poles involves a deep process of spiritual repair. The Acacia Brook was historically a place associated with disaster and immorality. Foreseeing the eventual construction of the Tabernacle, Jacob brought acacia trees with him down to Egypt and planted them there. His intention was for his descendants to take this specific wood with them when they eventually left. By using these trees for a holy purpose, the Israelites weakened the negative energy of the Acacia Brook and protected themselves from future spiritual failure, transforming a symbol of sin and corruption into a powerful instrument of atonement and healing. Furthermore, the very name of the wood hints at a remarkable event during the Exodus. The massive trees were far too heavy and large for human beings to carry on their own. Instead, they miraculously floated across the sea, crossing the waters by themselves [שפתי כהן].
