1 Samuel 24:2-5

2So Saul took 3,000 chosen men from all Israel and went to search for David and his men near the rocks of the mountain goats.

3When he came across the sheepfolds along the way where there was a cave, Saul went in to relieve himself. Now David and his men were already sitting in the innermost parts of the cave.

4So David’s men said to him, “Look, it’s the day Adonai spoke to you about, ‘Behold, I will deliver your enemy into your hand, so you may do to him as seems good in your eyes.’” Then David crept and cut off the corner of Saul’s robe stealthily.

5But afterward, David’s conscience bothered him for cutting off the edge of Saul’s robe.
