1 Samuel 26:7-9

7 And Dawiḏ and Aḇishai came to the people by night and saw Sha’ul lying asleep within the camp, with his spear stuck in the ground by his head, and Aḇnĕr and the people lay all around him.

8 And Aḇishai said to Dawiḏ, “Elohim has surrendered your enemy into your hand this day. And now, please, let me strike him at once with the spear, right into the earth, and not a second time!”

9 But Dawiḏ said to Aḇishai, “Do not destroy him, for who shall stretch out his hand against the anointed of יהוה, and be guiltless?”
