And it came to pass on the second sabbath after the first, that he went through the grainfields; and his disciples plucked the ears of grain, and did eat, rubbing them in their hands. And certain of the Pharisees said unto them, Why do you that which is not lawful to do on the sabbath days? And Jesus answering them said, Have you not read so much as this, what David did, when he was hungry, and they who were with him; How he went into the house of God, and did take and eat the showbread, and gave also to them that were with him; which it is not lawful to eat, but for the priests alone? And he said unto them, The Son of man is Lord also of the sabbath.

And it came to pass also on another sabbath, that he entered into the synagogue and taught: and there was a man whose right hand was withered. And the scribes and Pharisees watched him, whether he would heal on the sabbath day; that they might find an accusation against him. But he knew their thoughts, and said to the man who had the withered hand, Rise up, and stand forth in the midst. And he arose and stood forth. Then said Jesus unto them, I will ask you one thing; Is it lawful on the sabbath days to do good, or to do evil? to save life, or to destroy it? And looking round about upon them all, he said unto the man, Stretch forth your hand. And he did so: and his hand was restored whole as the other.

And they were filled with fury; and discussed one with another what they might do to Jesus. And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God. And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles; Simon, (whom he also named Peter,) and Andrew his brother, James and John, Philip and Bartholomew, Matthew and Thomas, James the son of Alphaeus, and Simon called Zelotes, And Judas the brother of James, and Judas Iscariot, who also was the traitor. (Luke 6:1-16)
