Matthew15chapter 15

The handwashing at issue was not hygiene and not the written Law. It was a ritual pouring of water over the hands before eating, part of the body of custom the Pharisees called the tradition of the elders — practice they held was handed down alongside Moses. Ordinary Galileans were lax about it; the Pharisees were not.

The counter-charge Jesus makes concerns a real legal device. A man could declare property korban, dedicated to God, which put it out of reach for other uses — including the support he owed his aged parents. A first-century burial box found near Jerusalem carries that very word in an inscription, showing the term was in everyday use. The vow was binding, so the loophole held, and the commandment about honouring father and mother quietly died in it.

The trip north was a deliberate crossing of a border. Tyre and Sidon were prosperous Phoenician port cities on the Mediterranean coast, thoroughly Gentile, and there was old resentment between their wealthy merchants and the Galilean farmers who supplied their grain.

The exchange with the mother turns on a word choice. The term used is not the street scavenger but the small dog kept in a house, under the table where the family eats. She takes the picture and works inside it: the household pets do get the scraps, and she is asking only for scraps.
