St. Pius X

1 Now it happened that, on the second first Sabbath,
as he passed through the grain field, his disciples were separating the
ears of grain and eating them, by rubbing them in their hands.
2 Then certain Pharisees said to them, “Why are you doing what is not lawful on the Sabbaths?”
3 And responding to them, Jesus said: “Have you not read this, what
David did when he was hungry, and those who were with him?
4 How he entered into the house of God, and took the bread of the
Presence, and ate it, and gave it to those who were with him, though it
is not lawful for anyone to eat it, except the priests alone?”
5 And he said to them, “For the Son of man is Lord, even of the Sabbath.”
