Mark 2:23-26

23On the Sabbath he was going through the grainfields, and his disciples began to make their way, picking some heads of grain.

24The Pharisees said to him, “Look, why are they doing what is not lawful on the Sabbath?”

25He said to them, “Have you never read what David and those who were with him did when he was in need and hungry —

26how he entered the house of God in the time of Abiathar the high priest and ate the bread of the Presence — which is not lawful for anyone to eat except the priests — and also gave some to his companions?”
