1 Samuel 21:6-9

6So the priest gave the holy bread to David because he did not have any other bread. This was the bread which had been on the table in the Lord's tent. The priest would take it from there each day and he would put hot, fresh bread in its place.

7One of Saul's servants was there that day. His name was Doeg. He came from Edom. He was the leader of Saul's shepherds. He was staying in Nob to make offerings to the Lord.

8David asked the priest, Ahimelech, ‘Is there any sword or spear here that I could take? The king sent me quickly to do an important job. So I left home without my sword or any other weapon.’

9Ahimelech answered, ‘The sword of Goliath the Philistine is here. After you killed him in the valley of Elah, we kept the sword here. We covered it with a cloth and we put it behind the ephod. If you want it, you can take it. We do not have any other weapon except that one.’ David said, ‘Give it to me. There is no sword as good as that one.’
