V.1-11 The well-known story of Goliath.
V.11 The result of not trusting the Lord. Like us, sometimes?
V.12-27 Jesse was thinking about his sons in the army, and he sends David with a message and a present. From now on David is a picture of Christ.
V.26 While all the others trembled and were afraid, David knew the living God was on the side of Israel and was not afraid.
V.28-29 His brothers accuse him of carelessness and pride. The Lord Jesus “came unto His own, and His own received Him not” (John 1:1111He came unto his own, and his own received him not. (John 1:11)).
V.30-39 Saul suggests that David put on the king’s own armor. But David takes it all off, for he would not dare to go in the strength and armor of men, but in the power of God. He says “the Lord ... will deliver me.” Have you ever faced a temptation in your own strength and found how weak you were? But if we trust in the strength of the Lord, there will be victory.
V.40 David picks out five smooth stones and has them ready in his bag. It is a good thing to have the Word of God ready to meet any attack of the enemy.
V.49 With one of these stones, the victory is won! David is a beautiful picture of our Lord Jesus who went into the valley of death to defeat our mighty enemy. At the cross He defeated Satan and death, and now we share the wonderful victory.
