1 Samuel 26:4-6

4 So David sent out spies to know for certain that Saul had come after him again.

5 Then David went to where Saul had set up his camp. David saw where Saul and Abner were sleeping. (Abner son of Ner was the commander of Saul’s army.) Saul was sleeping in the center of a circle of men that surrounded him.

6 David talked to Ahimelech the Hittite and Abishai son of Zeruiah. (Abishai was Joab’s brother.) He asked them, “Who would like to go down into the camp with me after Saul?” Abishai answered, “I’ll go with you.”
