Mark2:25-26: He answered, “Have you never read what David did when he and his companions were hungry and in need? In the days of Abiathar the high priest, he entered the house of God and ate the consecrated bread, which is lawful only for priests to eat. And he also gave some to his companions.”
1 Samuel 21:1-5 : “Then came David to Nob to Ahimelech the priest: and Ahimelech was afraid at the meeting of David, and said to him, Why are you alone, and no man with you? And David said to Ahimelech the priest, The king has commanded me a business, and has said to me, Let no man know any thing of the business about which I send you, and what I have commanded you: and I have appointed my servants to such and such a place.Now therefore what is under your hand? give me five loaves of bread in my hand, or what there is present. And the priest answered David, and said, There is no common bread under my hand, but there is hallowed bread; if the young men have kept themselves at least from women.And David answered the priest, and said to 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, yes, though it were sanctified this day in the vessel.”
St. Mark talks about David’s companions, But 1 Samuel 21:1 says that he was alone.
