Psalm 133 stands as a powerful expression of the beauty and importance of unity among brethren. How good and how pleasant it is for brethren to dwell together in unity, as the first verse declares, setting a tone of hope and aspiration for harmony among God's people. This unity is not merely a suggestion but a profound goal, reflecting what is proper, fitting, and attractive in God's sight. It brings great pleasure and benefits to those who are joined together, emphasizing the rightness and loveliness of such togetherness. The psalm, one of the fifteen Songs of Ascents, holds a significant place near the end of this series, suggesting that unity is a final hurdle before the ultimate fulfillment of God's plan. Verses 2 and 3 vividly illustrate this unity through the metaphors of oil and dew. The oil, running down upon Aaron's head, beard, and garments, symbolizes a proper and pleasant anointing, evoking a sweet aroma reserved for the high priest's consecration. This imagery portrays unity as something holy and set apart, descending from a higher place to cover the entire body. Similarly, the dew descending from Hermon to the mountains of Zion represents a refreshing and gentle covering, illustrating unity as a gift that spans from the highest to the lowest, encompassing all within the church. Furthermore, Psalm 133 concludes with the declaration that God commands His blessing of eternal life in Zion, underscoring that unity is vital to this divine promise. Unity is presented as a command from God, requiring a response from His people to work toward it, to promote and sustain it. Without this effort, unity cannot be achieved, even with the abundant outpouring of God's Spirit. Thus, the psalm calls for a collective striving toward harmony, reflecting the deep yearning for brethren to dwell together as one, in alignment with God's will.
