Mark 2:23-26

And it happened that He was passing through the grainfields on the Sabbath, and His disciples began to make their way along while picking the heads of grain. The Pharisees were saying to Him, “Look, why are they doing what is not lawful on the Sabbath?” And He *said to them, “Have you never read what David did when he was in need and he and his companions became hungry; how he entered the house of God in the time of Abiathar the high priest, and ate the consecrated bread, which is not lawful for anyone to eat except the priests, and he also gave it to those who were with him?”
