A KING REJECTED, FORESHADOWING A KING REJECTED.
2 Samuel 2:11 And the time that David was king in Hebron over the house of Judah was seven years and six months.
Matthew Henry:
Here is, I. A rivalship between two kings - David, whom God made king, and Ishbosheth, whom Abner made king. One would have thought, when Saul was slain, and all his sons that had sense and spirit enough to take the field with him, David would come to the throne without any opposition, since all Israel knew, not only how he had signalized himself, but how manifestly God had designated him to it; but such a spirit of contradiction is there, in the devices of men, to the counsels of God, that such a weak and silly thing as Ishbosheth, who was not thought fit to go with his father to the battle, shall yet be thought fit to succeed him in the government, rather than David shall come peaceably to it. Herein David's kingdom was typical of the Messiah's, against which the heathens rage and the rulers take counsel, Psa_2:1, Psa_2:2.
AND his concise commentary:
The nation in general refused David. By this the Lord trained up his servant for future honour and usefulness; and the tendency of true godliness was shown in his behaviour while passing through various difficulties. David was herein a type of Christ, whom Israel would not submit to, though anointed of the Father to be a Prince and a Saviour to them
