2 Samuel 1:9-10

9He said to me, ‘Stand up facing me and kill me, for [terrible] agony has come over me, yet I still live [and I will be taken alive].’

10So I stood facing him and killed him, because I knew that he could not live after he had fallen. Then I took the crown which was on his head and the band which was on his arm, and I have brought them here to my lord.”
