1 Samuel 26:4-6

New Revised Standard Version Catholic Edition

⁴ David sent out spies, and learned that Saul had indeed arrived. ⁵ Then David set out and came to the place where Saul had encamped; and David saw the place where Saul lay, with Abner son of Ner, the commander of his army. Saul was lying within the encampment, while the army was encamped around him.

⁶ Then David said to Ahimelech the Hittite, and to Joab’s brother Abishai son of Zeruiah, “Who will go down with me into the camp to Saul?” Abishai said, “I will go down with you.”
