1st Samuel 24:6

3 Then Saul took three thousand of the best men out of all Israel, and went in search of David and his men on the rocks of the mountain goats.

4 And on the way he came to a place where sheep were kept, where there was a hollow in the rock; and Saul went in for a private purpose. Now David and his men were in the deepest part of the hollow.

5 And David's men said to him, Now is the time when the Lord says to you, I will give up your hater into your hands to do with him whatever seems good to you. Then David, getting up, took the skirt of Saul's robe in his hand, cutting off the end of it without his knowledge.

6 And later, David was full of regret for cutting off Saul's skirt.

7 And David said to his men, Before the Lord, never let it be said that my hand was lifted up against my lord, the man of the Lord's selection, for the Lord's holy oil has been put on him.

8 So with these words David kept his servants back, and did not let them make an attack on Saul. And Saul got up and went on his way.

9 And after that David came out of the hollow rock, and crying after Saul said, My lord the king. And when Saul gave a look back, David went down on his face and gave him honour.
