1 Samuel 26:4-6

4 he sent some spies to find out if it was true.

5 Then he sneaked up to Saul’s camp. He noticed that Saul and his army commander Abner the son of Ner were sleeping in the middle of the camp, with soldiers sleeping all around them.

6 David asked Ahimelech the Hittite and Joab’s brother Abishai, [2] “Which one of you will go with me into Saul’s camp?” “I will!” Abishai answered.
