1 Samuel 23:9

Then Saul said to Ahijah, “Bring the ark of God here.” For the ark of God was at that time with the sons of Israel.

But one son of Ahimelech the son of Ahitub, named Abiathar, escaped and fled after David.

So David asked of Yahweh, saying, “Shall I go and strike these Philistines?” And Yahweh said to David, “Go and strike the Philistines and save Keilah.”

Then David said to Abiathar the priest, the son of Ahimelech, “Please bring the ephod near to me.” So Abiathar brought the ephod near to David.

Now it happened afterwards that David asked of Yahweh, saying, “Shall I go up to one of the cities of Judah?” And Yahweh said to him, “Go up.” So David said, “Where shall I go up?” And He said, “To Hebron.”

Then to Abiathar the priest the king said, “Go to Anathoth to your own field, for you deserve to die; but I will not put you to death at this time, because you carried the ark of Lord Yahweh before my father David, and because you were afflicted in everything with which my father was afflicted.”

For the sons of Israel will remain for many days without king or prince, without sacrifice or sacred pillar, and without ephod or household idols.
