David Kills Goliath

171 Now the Philistines gathered their armies together to battle, and were gathered together at Sochoh, which belongs to Judah; they encamped between Sochoh and Azekah, in Ephes Dammim. 2 And Saul and the men of Israel were gathered together, and they encamped in the Valley of Elah, and drew up in battle array against the Philistines. 3 The Philistines stood on a mountain on one side, and Israel stood on a mountain on the other side, with a valley between them. 4 And a champion went out from the camp of the Philistines, named Goliath, from Gath, whose height was six cubits and a span.

Commentary on 1 Samuel 17:1-11

(Read 1 Samuel 17:1-11)

Men so entirely depend upon God in all things, that when he withdraws his help, the most valiant and resolute cannot find their hearts or hands, as daily experience shows.
