Matt 12:1-8,
At that time Jesus went through the grainfields on the Sabbath, and His disciples became hungry and began to pick the heads of grain and eat. But when the Pharisees saw this, they said to Him, “Look, Your disciples do what is not lawful to do on a Sabbath.” But He said to them, “Have you not read what David did when he became hungry, he and his companions, how he entered the house of God, and they ate the consecrated bread, which was not lawful for him to eat nor for those with him, but for the priests alone? Or have you not read in the Law, that on the Sabbath the priests in the temple break the Sabbath and are innocent? But I say to you that something greater than the temple is here. But if you had known what this means, ‘I desire compassion, and not A sacrifice,’ you would not have condemned the innocent. Lord of the Sabbath For the Son of Man is Lord of the Sabbath.”
In this passage we see the Pharisees condemn the disciples of breaking the Torah by picking grain and eating it on the sabbath. Then Yeshua asks them in short, my translation, “did David and his men break Torah when they ate the consecrated bread, which would include the high priest who gave David the consecrated bread”. He continues, “Are the priests in the temple guilty of breaking Torah every Sabbath when they work in the Temple”. And lastly, “is Yeshua (Jesus) guilty of breaking Torah by healing on or allowing his disciples to pick grain on the Sabbath”?
