Matthew 12:1-4

112At that time Jesus went through the grainfields on the Sabbath, and His disciples became hungry and began to 3pick the heads of grain and eat.

2Now when the Pharisees saw this, they said to Him, “Look, Your disciples are doing what 4is not lawful to do on a Sabbath!”

3But He said to them, “Have you not read what David did when he became hungry, he and his companions--

4how he entered the house of God, and 5they ate the 6consecrated bread, which was not lawful for him to eat nor for those with him, but for the priests alone?
