Now [Saul’s cousin] Abner the son of Ner, commander of Saul’s army, had taken Ish-bosheth the son of Saul and brought him over to Mahanaim.

Now Abner the son of Ner and the servants of Ish-bosheth the son of Saul went out from Mahanaim to Gibeon.

When Joab and all the army that was with him arrived, they told Joab, “Abner the son of Ner came to the king, and he has sent him away, and he has gone in peace.”

You know Abner the son of Ner, that he [only] came to deceive you [with flattering words] and to learn of your going out and coming in, and to find out what you are doing.”

Afterward, when David heard of it, he said, “I and my kingdom are forever innocent before the Lord of the blood of Abner the son of Ner.

So all the people and all Israel understood that day that it had not been the will of the king to put Abner the son of Ner to death.
