This Giant, Goliath of Gath, appeared every day for forty days, defying the Armies of Israel, and challenging them to send out a man to fight with him. The Giant struck terror into the hearts of the Armies of Israel. Now there was a youth named David, ruddy and beautiful, who was on the Mountains of Palestine, tending his father's flocks. As he sat watching the sheep, the Holy Spirit taught him many of the Psalms we all love, such as, "The Lord is my Shepherd." One day a lion came out of his lair and took a lamb of the flock, and David, knowing that God was his strong Helper, went out after the lion, and smote him and got the lamb out of his mouth, and when the lion turned on him, David caught him by the beard and killed him. And a bear came in the same way, and he killed him too. One day David's father, Jesse, sent him to see how his brothers, who were at the war, were getting on; and when he reached the Camp, the first thing that he heard was the news of this dreadful Giant, who was defying the Israelites every morning and every evening. And David said, "Who is this heathen Philistine, that he should defy the Armies of the Living God?" David's eldest brother was angry with him for what he said; but David's words were heard by the other soldiers, and they repeated them to King Saul. And Saul sent for him, and when David came into his presence, he said to the King, "Let no man's heart fail him because of the Giant, I will go and fight with him!" [Illustration: The giant struck terror into the hearts of the armies of Israel.] But Saul looked at David and said, "You are not able to fight with the Giant." Then David told the King about the lion and bear, and he said, "The Lord that delivered me out of the paw of the lion, and out of the paw of the bear, He will deliver me out of the hand of this Philistine." So Saul agreed to his going, and put some armour on him; but David told the King he could not go with these, for he was not used to armour. Then David took his staff in his hand, and went to the brook and chose out five smooth stones, and he put them in his shepherd's bag that hung at his side. Before we go on to what David did with those stones, there are two or three interesting things in this story which we shall do well to notice; for they will be, if we think of them, a great help to us in our own lives. We all have, like David, a tremendous enemy to face. This is Satan; and he comes to us every day, like the Giant Goliath, and he tries to make us afraid. He wants us to live without thinking about God; he wants us to forget that there is a great Helper for us in every time of need. But David truly loved God with his whole heart, and he was very brave; but it was in God's strength that he had determined to meet the Giant. So he went to the brook, and chose some of the smooth stones that he was accustomed to use.
