1 Samuel 17:31-33

Revised Standard Version

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