6 Now it happened that He was passing through some grainfields on a Sabbath; and His disciples were picking the heads of grain, rubbing them in their hands, and eating the grain. 2 But some of the Pharisees said, “Why do you do what is not lawful on the Sabbath?” 3 And Jesus answering them said, “Have you not even read what David did when he was hungry, he and those who were with him, 4 how he entered the house of God, and took and ate the [a]consecrated bread which is not lawful for any to eat except the priests alone, and gave it to his companions?” 5 And He was saying to them, “The Son of Man is Lord of the Sabbath.”
The other passage today is around Nehemiah shutting the gates of Jerusalem and keeping the merchants out so there would be a day of rest, a sabbath. In the modern society, where there is pressure for all shops to be open for extended hours all days regardless of the cost to the owner or workers, Nehemiah gives is a correction.
In the more conservative parts on NZ, it is only the malls that open on Sunday. And the dairies (convenience stores), petrol stations included. It is healthier for society.
For the son of man is Lord of the sabbath, not the corporations.
