So David and Abishai came to the people by night
and, behold, Saul lay sleeping within the trench;
(See Gill on 1 Samuel 26:5);
and his spear stuck in the ground at his bolster;
ready to take up and defend himself, should he be surprised; or this was his sceptre, which he always carried about with him, as an ensign of royalty, and by which very probably David knew which was Saul's tent or couch, where he slept:
but Abner and the people lay round about him;
as in ( 1 Samuel 26:5 ) .
