John's disciples and the Pharisees had a habit of fasting. Some people asked Jesus, "Why do John's disciples and the Pharisees' disciples fast, but yours don't?"
Jesus said, “The wedding guests can't fast while the groom is with them, can they? As long as they have the groom with them, they can't fast. 20But the days will come when the groom will be taken away from them, and then they will fast. 21
"No one sews a piece of new, unshrunk cloth on old clothes; otherwise, the patch tears away from it, the new from the old, and makes a worse tear.22 No one pours new wine into old leather wineskins; otherwise, the wine would burst the wineskins and the wine would be lost and the wineskins destroyed. But new wine is for new wineskins."
Jesus went through the wheat fields on the Sabbath. As the disciples made their way, they were picking the heads of wheat.
The Pharisees said to Jesus, "Look! Why are they breaking the Sabbath law?"
He said to them, "Haven't you ever read what David did when he was in need, when he and those with him were hungry?26 During the time when Abiathar was high priest, David went into God's house and ate the bread of the presence, which only the priests were allowed to eat. He also gave bread to those who were with him."
Then he said, "The Sabbath was created for humans; humans weren't created for the Sabbath.28 This is why the Human Onea is Lord even over the Sabbath."
