For I have brought neither my sword nor my weapons with me, because the king’s mission was urgent.” 9The priest replied, “The sword of Goliath the Philistine, whom you killed in the Valley of Elah, is here; it is wrapped in a cloth behind the ephod. If you want, you may take it. For there is no other but this one here.” 10That day David fled from Saul and went to Achish king of Gath. 11But the servants of Achish said to him, “Is this not David, the king of the land?

Why have you brought him to me? 15Am I in need of madmen, that you have brought this man to rave in my presence? Must this man come into my house?”
