1 Chronicles 10:3

And the battle went sore against Saul, and the archers hit him, and he was wounded of the archers.

Cross-reference

1 Samuel 31:3-6 gives a parallel account: 'the battle pressed hard... archers found him, he was wounded'.

2 Samuel 1:4-10 offers a different account — an Amalekite claims to have killed Saul after he was wounded.
