And Abner sent messengers to David on his behalf,.... On his own account, and not on the account of Ishbosheth, or the people of Israel; but to obtain terms for himself, or in his own name, as representing him and standing in his stead; or secretly, as Kimchi explains it, unknown to Ishbosheth, or the people of Israel.
