One camp got used to being afraid.
Two armies face each other across the valley of Elah. Morning and evening for forty days, the Philistine champion Goliath walks out in bronze armor with the same offer. Send one man. If he kills me, we serve you. If I kill him, you serve us.
Saul and all Israel hear it and are badly afraid. When Goliath appears, the men run. Saul's answer is a rich reward for whoever will fight. Under Goliath's terms, a king who fought in person would stake the whole army on himself.
David asks out loud, and keeps asking.
David has not come as a soldier. His father sent him with food for his brothers. He arrives, hears the challenge, and the men around him run. Then he asks out loud what will be done for the man who kills this Philistine and lifts Israel's disgrace.
His eldest brother Eliab turns on him in anger: you are proud, you only came to watch the battle. The narrator never rules on that charge. David answers with a question of his own, what has he done now, and turns to the next man with the same question until his words reach Saul.
He asks twice about the reward: riches, the king's daughter, freedom for his father's house. But every reason he gives is about Israel's disgrace and a challenge to the living God. The chapter keeps both in plain view.
He leaves the borrowed armor behind.
Saul objects that David is a youth and Goliath has been a fighting man since his own youth. It is a fair reading of the odds. David answers with a record: a lion and a bear took a lamb from his father's flock, and he went after them and killed them.
Saul puts his own armor on him. David tries to walk in it, says he has not tested it, and takes it off. He goes out with his staff, a sling and five smooth stones. Ancient slings could kill, but the narrator still stresses the gap: there was no sword in David's hand.
David does not credit his own skill. The LORD who saved him from the lion and the bear, he says, will save him from this Philistine, because the battle is the LORD's. A tested record and chosen tools on one side; his insistence that it is the LORD who delivers, on the other. Both stand.
The text never says what he felt.
Fear gets named twice in this chapter, in Saul's camp and in the men who run. For David there is only speech and action. He volunteers, argues, picks his gear and runs toward Goliath.
The common reading is that trust in God gave him courage, and his own words make that fair. Psychologist Cynthia Pury offers a second angle: courage is choosing to act toward a worthwhile goal despite a known risk. Fear is common but not required, and its absence is not the test. If that is right, you do not have to wait to feel brave.
