Life is cyclical. Many of the physical challenges experienced by young children will once again be encountered by those who live long enough. As a person ages, many things taken for granted long ago in the prime of life begin to deteriorate. For instance, the Bible says that Israel’s eyes “were dim for age” (Genesis 48:10), Barzillai’s hearing and taste buds were ill affected (2 Samuel 19:34-35), and David “gat no heat” (1 Kings 1:1) as he grew old. For these reasons and others, the Bible emphasizes that aged saints are “old and well stricken in age” (Genesis 18:11). In other words, the passing of time or the coming of age strikes the physical well-being of the body and its physical and mental functions. This physical and mental degeneration is the fulfillment of the cycle of life as the body prepares to return to the dust from whence it originally came (Ecclesiastes 12:7).
The psalmist proclaims: “Behold, how good and how pleasant it is for brethren to dwell together in unity!” Unlike the unity of unbelievers and the heathen, the Lord rejoices in the righteous unity of His people. King David was someone who knew and experienced the difficulties of division. He spent a great deal of his life running from a king and those who were against him. Even in the beginning of his reign, the people were divided (2 Samuel 2:8-11). It was not until 7 1/2 years later that the people were united in David (2 Samuel 5:1-5). When the people dwelt in unity, David rejoiced. He likened it to the source of spiritual life for the nation of Israel, the priesthood (Psalm 133:2), and to the source of physical life in the dew of Hermon (Psalm 133:3). In other words, the right kind of unity gave life and hope to the nation!
