1 Samuel 23:6

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.”

But David knew that Saul was plotting evil against him; so he said to Abiathar the priest, “Bring the ephod here.”

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.

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.”
