1 Samuel 17:31-33

New Revised Standard Version, Anglicised

³¹ When the words that David spoke were heard, they repeated them before Saul; and he sent for him. ³² David said to Saul, ‘Let no one’s heart fail because of him; your servant will go and fight with this Philistine.’ ³³ Saul said to David, ‘You are not able to go against this Philistine to fight with him; for you are just a boy, and he has been a warrior from his youth.’
