I Samuel 21:1-3, 7-9

Now David came to Nob, to Ahimelech the priest. And Ahimelech was afraid when he met David, and said to him, “Why are you alone, and no one is with you?” So David said to Ahimelech the priest, “The king has ordered me on some business, and said to me, ‘Do not let anyone know anything about the business on which I send you, or what I have commanded you.’ And I have directed my young men to such and such a place. Now therefore, what have you on hand? Give me five loaves of bread in my hand, or whatever can be found.”

Now a certain man of the servants of Saul was there that day, detained before the LORD. And his name was Doeg, an Edomite, the chief of the herdsmen who belonged to Saul. And David said to Ahimelech, “Is there not here on hand a spear or a sword? For I have brought neither my sword nor my weapons with me, because the king’s business required haste.” So the priest said, “The sword of Goliath the Philistine, whom you killed in the Valley of Elah, there it is, wrapped in a cloth behind the ephod. If you will take that, take it. For there is no other except that one here.” And David said, “There is none like it; give it to me.”
