1 Samuel 26:5-7

5One night, David went secretly to Saul's camp. Saul was asleep in the middle of the tents. The leader of his army, Ner's son Abner, was with him. He was asleep too. The army was all around them. David could see all this.

6David spoke to two of his men. One of them was Ahimelech, a Hittite man. The other man was Abishai, who was Joab's brother (Zeruiah was their mother). David asked them, ‘Which one of you will go down into Saul's camp with me?’ Abishai said, ‘I will come with you.’

7So David and Abishai went among Saul's army that night. They saw that Saul was asleep in the middle of the camp. He had pushed his spear into the ground near his head. Abner and the army were asleep around Saul.
