The successor of King Saul

[CyrilSebastian]

If the Lord had not chosen David to be the King of Israel after King Saul and King Saul had remained as monarch, would Jonathan have become king after his father Saul?

[CyrilSebastian]

Jonathan was the eldest son of King Saul.   
Saul died at the Battle of Mount Giolboa.   
 Three of Saul's sons: Jonathan, Abinadab, and Malchishua died with Saul at Mount Gilboa.     
Ish-bosheth, son of Saul, was proclaimed king of Israel after the slaying of his father and brothers   
In the battle of Gilboa, Ish-bosheth reigned for two years.

[CyrilSebastian]

After the demise of King Saul. the tribe of Judah seceded from the rule of the   
House of Saul by proclaiming David as its king and war ensued.

Ish-bosheth was 40 years old when he was proclaimed King over Israel.
