Bring me my wife Michal, who I bought for a hundred Philistine foreskins.
15-16 So Ishbosheth took Michal from her husband, Phaltiel, who went along weeping behind her.
Joab kills Abner
20 David and Abner met to discuss their plans to steal Israel from Ishbosheth.
24 When David's captain, Joab, heard about the agreement between David and Abner, he was angry. He didn't trust Abner and thought he was trying to deceive David.
26 So Joab sent messengers to Abner asking him to return to Hebron.
27 When Abner came to Hebron, Joab took him aside to speak to him quietly. Then Joab smote him under the fifth rib.
28 David proclaimed himself guiltless and condemned Joab, saying:
Let the blame rest on the head of Joab, and on his whole family, and on all of his descendants forever.
29 May all of his descendants have discharges from their penises, be lepers, lean on a staff, commit suicide, or starve to death.
30 (The reason Joab wanted to kill Abner was that Abner smote his brother Asahel under the fifth rib, when he refused to turn to the right or the left.)
31-32 David said to Joab and all of the people with him,
35 All the people brought David meat to eat. But David said,
I swear to God that I won't eat until the sun goes down.
36 This pleased the people, as everything that David did pleased all of the people.
A few more words about this episode
Saul's son, Ishbosheth (3:1)
Ishbotheth was Saul's only surviving son and became the king of Israel when Saul died.
David had six sons in Hebron. (3:2)
According to 2 Sam 5:5, David reigned for 7 years and six months in Hebron.
The Bible doesn't say whether he had any daughters in Hebron.
Up to now, we've known about three of David's wives: Michal, who Saul sold to David for 200 Philistine foreskins, but who was later given by Saul to another man; Abigail, who became David's wife after God killed her husband, Nabal; and Ahinoam, who David just somehow acquires when he took Abigail.
