1 Samuel 11:13

Now Saul had taken the kingdom over Israel, and he fought against all his enemies on every side, against Moab, the sons of Ammon, Edom, the kings of Zobah, and the Philistines; and wherever he turned, he inflicted punishment.

“For he took his life in his hand and struck the Philistine, and Yahweh brought about a great salvation for all Israel; you saw it and were glad. Why then will you sin against innocent blood by putting David to death without a cause?”

Then the inhabitants of Jabesh-gilead heard what the Philistines had done to Saul,

David then said, “What have I to do with you, O sons of Zeruiah, that you should this day be an adversary to me? Should any man be put to death in Israel today? For do I not know that I am king over Israel today?”

He arose and struck the Philistines until his hand was weary and clung to the sword, and Yahweh brought about a great salvation that day; and the people returned after him only to strip the slain.
