1 Samuel 17:40

17:40 He took his staff in his hand, picked out five smooth stones from the stream, placed them in the pouch ¹  of his shepherd’s bag, took his sling in hand, and approached the Philistine.

1 Samuel 17:49-50

17:49 David reached his hand into the bag and took out a stone. He slung it, striking the Philistine on the forehead. The stone sank deeply into his forehead, and he fell down with his face to the ground.

17:50 ² David prevailed over the Philistine with just the sling and the stone. He struck down the Philistine and killed him. David did not even have a sword in his hand. ³ 

[17:40]  ¹ tn This Hebrew word occurs only here and its exact meaning is not entirely clear. It refers to a receptacle of some sort and apparently was a common part of a shepherd’s equipment. Here it serves as a depository for the stones that David will use in his sling.

[17:50]  ² tc Most LXX mss lack v. 50.

[17:50]  ³ tn Verse 50 is a summary statement; v. 51 gives a more detailed account of how David killed the Philistine.
