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!
The Bible records Jonathan and David's strikingly close friendship like that of siblings. Regardless of this cherished relationship, Jonathan's father, king Saul, feared and despised David. Both king Saul and his son died during battle, thus paving the way for David to ascend to the throne of Israel. Once David became king, he sought for an opportunity to show kindness to any of Jonathan’s remaining family members. After searching through the land, it was discovered that Saul and Jonathan had one remaining descendent (Mephibosheth). David sent for Mephibosheth and told him his intentions of showing him the kindness normally reserved for a member of the king's family. This act of kindness included the restoration of his family’s property. David’s kindness also made provision for Mephibosheth to eat at the king’s table (2 Samuel 9:7), “as one of the king’s sons” (2 Samuel 9:11). David’s kindness meant that Mephibosheth would be viewed and treated as a son. This demonstration of kindness illustrates God's act of kindness toward His beloved children through Christ Jesus.
