Who was high priest when David ate the holy bread?

David comes to Ahimelech the priest at Nob, who gives him the hallowed bread.

Then came David to Nob to Ahimelech the priest: and Ahimelech was afraid at the meeting of David, and said unto him, Why art thou alone, and no man with thee? And David said unto Ahimelech the priest, The king hath commanded me a business, and hath said unto me, Let no man know any thing of the business whereabout I send thee, and what I have commanded thee: and I have appointed my servants to such and such a place. Now therefore what is under thine hand? give me five loaves of bread in mine hand, or what there is present. And the priest answered David, and said, There is no common bread under mine hand, but there is hallowed bread; if the young men have kept themselves at least from women. And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days, since I came out, and the vessels of the young men are holy, and the bread is in a manner common, yea, though it were sanctified this day in the vessel. So the priest gave him hallowed bread: for there was no bread there but the shewbread, that was taken from before the Lord, to put hot bread in the day when it was taken away.

Abiathar, a son of Ahimelech, alone escapes Saul’s massacre of the priests of Nob and flees to David.

And one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped, and fled after David. And Abiathar shewed David that Saul had slain the Lord’s priests. And David said unto Abiathar, I knew it that day, when Doeg the Edomite was there, that he would surely tell Saul: I have occasioned the death of all the persons of thy father’s house. Abide thou with me, fear not: for he that seeketh my life seeketh thy life: but with me thou shalt be in safeguard.

Jesus says David entered the house of God “in the days of Abiathar the high priest” and ate the shewbread.

And he said unto them, Have ye never read what David did, when he had need, and was an hungred, he, and they that were with him? How he went into the house of God in the days of Abiathar the high priest, and did eat the shewbread, which is not lawful to eat but for the priests, and gave also to them which were with him?

In David’s reign, Zadok and “Ahimelech the son of Abiathar” are the priests.

And Zadok the son of Ahitub, and Ahimelech the son of Abiathar, were the priests; and Seraiah was the scribe;
