Matthew 12:6

But he said to them, “Haven’t you read what David did when he was hungry, and those who were with him:

how he entered into God’s house and ate the show bread, which was not lawful for him to eat, nor for those who were with him, but only for the priests?

Or have you not read in the law that on the Sabbath day the priests in the temple profane the Sabbath and are guiltless?

But if you had known what this means, ‘I desire mercy, and not sacrifice,’ you wouldn’t have condemned the guiltless.

For the Son of Man is Lord of the Sabbath.”

He departed from there and went into their synagogue.
