1 Samuel 17:39-41

Amplified Bible, Classic Edition

³⁹ And David girded his sword over his armor. Then he tried to go, but could not, for he was not used to it. And David said to Saul, I cannot go with these, for I am not used to them. And David took them off.

⁴⁰ Then he took his staff in his hand and chose five smooth stones out of the brook and put them in his shepherd’s [lunch] bag [a whole kid’s skin slung from his shoulder], in his pouch, and his sling was in his hand, and he drew near the Philistine.

⁴¹ The Philistine came on and drew near to David, the man who bore the shield going before him.
