1 Chronicles 10:3

And the battle went sore against Saul, and the archers hit him; and he was sore wounded of the archers. Then said Saul unto his armourbearer, Draw thy sword, and thrust me through therewith; lest these uncircumcised come and thrust me through, and abuse me. But his armourbearer would not; for he was sore afraid. Therefore Saul took a sword, and fell upon it. And when his armourbearer saw that Saul was dead, he fell likewise upon his sword, and died with him. So Saul died, and his three sons, and his armourbearer, and all his men, that same day together.

And David said unto him, How went the matter? I pray thee, tell me. And he answered, That the people are fled from the battle, and many of the people also are fallen and dead; and Saul and Jonathan his son are dead also. And David said unto the young man that told him, How knowest thou that Saul and Jonathan his son be dead? And the young man that told him said, As I happened by chance upon mount Gilboa, behold, Saul leaned upon his spear; and, lo, the chariots and horsemen followed hard after him. And when he looked behind him, he saw me, and called unto me. And I answered, Here am I. And he said unto me, Who art thou? And I answered him, I am an Amalekite. He said unto me again, Stand, I pray thee, upon me, and slay me: for anguish is come upon me, because my life is yet whole in me. So I stood upon him, and slew him, because I was sure that he could not live after that he was fallen: and I took the crown that was upon his head, and the bracelet that was on his arm, and have brought them hither unto my lord.

Therefore the flight shall perish from the swift, and the strong shall not strengthen his force, neither shall the mighty deliver himself:
