1 Samuel 26:5-7

(5) And David arose, and came to the place where Saul had pitched: and David beheld the place where Saul lay, and Abner the son of Ner, the captain of his host: and Saul lay in the trench, and the people pitched round about him. (6) В¶ Then answered David and said to Ahimelech the Hittite, and to Abishai the son of Zeruiah, brother to Joab, saying, Who will go down with me to Saul to the camp? And Abishai said, I will go down with thee. (7) So David and Abishai came to the people by night: and, behold, Saul lay sleeping within the trench, and his spear stuck in the ground at his bolster: but Abner and the people lay round about him.

This bold attempt probably was from some secret influence imparted to David's mind. The sequel of the history of it proves, how sweet a lesson he gathered from it, and therefore it seems not improbable, that the Lord inclined his heart to the undertaking. Reader! it is very profitable at times to observe, how graciously the Lord leads on the minds of his people to do what they themselves would otherwise have never been competent to perform.
