1 Samuel 31:3-4

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.
