its travels

Abiathar  fled to David with an ephod in his hand. 

1 Samuel 23  David Saves the Town of Keilah

23 David heard that the Philistines were attacking the town of Keilah and were stealing the newly harvested grain. 2 So he asked the Lord, “Shall I go and attack the Philistines?”
“Yes,” the Lord answered. “Attack them and save Keilah.”
Then they told David, saying, Behold, the Philistines fight against Keilah, and they rob the threshingfloors.

3 And David's men said unto him, Behold, we be afraid here in Judah: how much more then if we come to Keilah against the armies of the Philistines? 4 Then David enquired of the Lord yet again. And the Lord answered him and said, Arise, go down to Keilah; for I will deliver the Philistines into thine hand.

⁵ So David and his men went to Keilah, and fought with the Philistines, and brought away their cattle, and smote them with a great slaughter. So David saved the inhabitants of Keilah. 6 And it came to pass, when Abiathar the son of Ahimelech fled to David to Keilah, that he came down with an ephod in his hand.

7 And it was told Saul that David was come to Keilah. And Saul said, God hath delivered him into mine hand; for he is shut in, by entering into a town that hath gates and bars.

⁸ And Saul called all the people together to war, to go down to Keilah, to besiege David and his men.
1 Samuel 23.9 (KJV) 9And David knew that Saul secretly practised mischief against him; and he said to Abiathar the priest, Bring hither the ephod.
