1 Samuel 26:4-6

New Century Version

⁴ he sent out spies and learned for certain that Saul had come to Hakilah.

⁵ Then David went to the place where Saul had camped. He saw where Saul and Abner son of Ner, the commander of Saul’s army, were sleeping. Saul was sleeping in the middle of the camp with all the army around him.

⁶ David asked Ahimelech the Hittite and Abishai son of Zeruiah, Joab’s brother, “Who will go down into Saul’s camp with me?”

Abishai answered, “I’ll go with you.”
