Meanwhile, Ner's son Abner, the commander of Saul's army, had taken Saul's son Ish-bosheth and brought him to Mahanaim.

Ner's son Abner and the servants of Saul's son Ish-bosheth set out from Mahanaim for Gibeon.

When Joab returned with his entire army, Joab was informed, "Ner's son Abner visited the king, and he has dismissed him. He has left in peace."

You know Ner's son Abner came to mislead you, to learn your troop movements, and to learn everything you're doing!"

Later on, David found out about it and proclaimed, "Let me and my kingdom remain guiltless forever in the LORD's presence for the death of Ner's son Abner.

As a result, the entire army and all of Israel understood that day that the king had nothing to do with the murder of Ner's son Abner.
