Surfing through the web, I found a cite from the bible on
http://www.bibleview.org/en/modules/Judges/26_Slingshot/which said:
As the Philistine moved closer to attack him, David ran quickly toward the battle line to meet him. 49 Reaching into his bag and taking out a stone, he slung it and struck the Philistine on the forehead. The stone sank into his forehead, and he fell facedown on the ground.
50 So David triumphed over the Philistine with a sling and a stone; without a sword in his hand he struck down the Philistine and killed him.
51 David ran and stood over him. He took hold of the Philistine’s sword and drew it from the scabbard. After he killed him, he cut off his head with the sword.
Now why does it say he killed him TWICE, when the shot with the stone would have finished Goliath? What does the second "killed" mean? Does he finish him with the sword, because he was only unconscious? Or does the second refer to the stone shot, which already killed him? Do you have any ideas?
