2nd Samuel 1:10

7 And when he looked behind him, he saw me, and called unto me. And I answered, Here am I.

8 And he said unto me, Who art thou? And I answered him, I am an Amalekite.

9 And he said unto me, Stand, I pray thee, beside me, and slay me; for anguish hath taken hold of me, because my life is yet whole in me.

10 So I stood beside 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.

11 Then David took hold on his clothes, and rent them; and likewise all the men that were with him:

12 and they mourned, and wept, and fasted until even, for Saul, and for Jonathan his son, and for the people of Jehovah, and for the house of Israel; because they were fallen by the sword.

13 And David said unto the young man that told him, Whence art thou? And he answered, I am the son of a sojourner, an Amalekite.
