1 Samuel 26:4-6

Revised Standard Version

⁴ David sent out spies, and learned of a certainty that Saul had come. ⁵ Then David rose and came to the place where Saul had encamped; and David saw the place where Saul lay, with Abner the 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 Ahim′elech the Hittite, and to Jo′ab’s brother Abi′shai the son of Zeru′iah, “Who will go down with me into the camp to Saul?” And Abi′shai said, “I will go down with you.”
