1 Samuel 17:50

So David prevailed over the Philistine with a sling and with a stone ,.... And with them only, without any other warlike weapon:

and smote the Philistine, and slew him ; smote him with the stone, which brought him to the ground, and then slew him with his own sword, as afterwards related:

but there was no sword in the hand of David ; when he engaged with the Philistine, and smote him, for he had put off all his armour, 1 Samuel 17:39 .
