2nd Samuel 1:10

7 And looking back, he saw me and gave a cry to me. And answering him I said, Here am I.

8 And he said to me, Who are you? And I said, I am an Amalekite.

9 Then he said to me, Come here to my side, and put me to death, for the pain of death has me in its grip but my life is still strong in me.

10 So I put my foot on him and gave him his death-blow, because I was certain that he would not go on living after his fall: and I took the crown from his head and the band from his arm, and I have them here for my lord.

11 Then David gave way to bitter grief, and so did all the men who were with him:

12 And till evening they gave themselves to sorrow and weeping, and took no food, weeping for Saul and for Jonathan, his son, and for the people of the Lord and for the men of Israel; because they had come to their end by the sword.

13 And David said to the young man who had given him the news, Where do you come from? And he said, I am the son of a man from a strange land; I am an Amalekite.
