1 Samuel 31:4 - Clarke's commentary and critical notes on the Bible

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. Draw thy sword, and thrust me through - Dr. Delaney has some good observations on this part of the subject: "Saul and his armor-bearer died by the same sword. That his armor-bearer died by his own sword is out of all doubt; the text expressly tells us so; and that Saul perished by the same sword is sufficiently evident. Draw Thy sword, says he to him, and thrust me through; which, when he refused, Saul, says the text, took The sword, (את החרב eth hachereb, the very sword), and fell upon it. What sword? Not his own, for then the text would have said so; but, in the plain natural grammatical construction, the sword before mentioned must be the sword now referred to, that is, his armor-bearer's, 1 Chronicles 10:4, 1 Chronicles 10:5. Now it is the established tradition of all the Jewish nation that this armor-bearer was Doeg, and I see no reason why it should be discredited; and if so, then Saul and his executioner both fell by that weapon with which they had before massacred the priests of God. So Brutus and Cassius killed themselves with the same swords with which they stabbed Caesar; and Calippus was stabbed with the same sword with which he stabbed Dio."
