2nd Samuel 2:8 But Abner the son of Ner, captain of Saul's host, took Ishbosheth the son of Saul, and brought him over to Mahanaim; 9 And made him king over Gilead, and over the Ashurites, and over Jezreel, and over Ephraim, and over Benjamin, and over all Israel.
[Patriarchs & Prophets pp 698] The Philistines did not oppose the action of Judah in making David king. They had befriended him in his exile, in order to harass and weaken the kingdom of Saul, and now they hoped that because of their former kindness to David the extension of his power would, in the end, work to their advantage. But David's reign was not to be free from trouble. With his coronation began the dark record of conspiracy and rebellion. David did not sit upon a traitor's throne; God had chosen him to be king of Israel, and there had been no occasion for distrust or opposition.
Yet hardly had his authority been acknowledged by the men of Judah, when through the influence of Abner, Ishbosheth, the son of Saul, was proclaimed king, and set upon a rival throne in Israel. Ishbosheth was but a weak and incompetent representative of the house of Saul, while David was pre-eminently qualified to bear the responsibilities of the kingdom. Abner, the chief agent in raising Ishbosheth to kingly power, had been commander-in-chief of Saul's army, and was the most distinguished man in Israel.
Abner knew that David had been appointed by the Lord to the throne of Israel, but having so long hunted and pursued him, he was not now willing that the son of Jesse should succeed to the kingdom over which Saul had reigned. The circumstances under which Abner was placed served to develop his real character and showed him to be ambitious and unprincipled. He had been intimately associated with Saul and had been influenced by the spirit of the king to despise the man whom God had chosen to reign over Israel.
2nd Samuel 2:10 Ishbosheth Saul's son was forty years old when he began to reign over Israel, and reigned two years. But the house of Judah followed David.
May God add His blessing to the study of His word. "Good night" and God bless!
