Joy and Delight: The psalm opens with, "Behold, how good and how pleasant it is for brethren to dwell together in unity!" This line captures a deep sense of joy and satisfaction that comes from harmonious relationships among people.
Peace and Serenity: The comparisons made in the psalm—to the precious ointment upon the head and the dew of Hermon—evoke a sense of calm and tranquility, suggesting that unity brings a refreshing and soothing effect, much like dew or a calming fragrance.
Reverence and Sacredness: The reference to the anointing oil running down Aaron's beard and garments (a ritual in consecrating a priest) adds a dimension of holiness and reverence. It reflects the sacredness of communal harmony as something blessed by God.
Overall, Psalm 133 expresses a profound appreciation for the emotional and spiritual benefits of unity, likening it to sacred rituals and refreshing natural phenomena, and ultimately suggests that such harmony is a blessing from God.
