Mark 2:28 Meaning

26How he went into the house of God in the days of Abiathar the high priest, and did eat the shewbread, which is not lawful to eat but for the priests, and gave also to them which were with him?

27And he said unto them, The sabbath was made for man, and not man for the sabbath:

28Therefore the Son of man is Lord also of the sabbath.
