The dissatisfaction with the rule of David"s house that had been brewing for years (cf. 2 Samuel 20:1) finally boiled over. Perhaps Rehoboam sent Adoram to pacify the angry mob ( 1 Kings 12:18). Whatever his reason, this proved to be "the straw that broke the camel"s back."[source]
Rehoboam lacked wisdom because he did not give God the place He deserved in his life. Because he revolted against God, the people revolted against him. In rebelling against Rehoboam, however, the Israelites were rebelling against God"s anointed king. That action could only bring divine discipline on them, and it did. This rebellion continued throughout the history of the divided kingdom and accounts for much of the misery that the nation experienced. [1] Rehoboam"s coronation turned into a bloody lynching and inspired the coronation of his rival ( 1 Kings 12:20). [source][source][source]
