Nobody here discussed the significance of Samaria.
Samaria is the capital of the Northern Kingdom, the 10 tribes of Israel.
The capital of the Southern Kingdom (Judah, Bejamin) is Jerusalem, where the Jews reside.
Jesus always mention something about this place… “The samaritan woman at the well”, “The good samaritan”, “The samaritan woman who said something about the crumbs given to the dogs”…
We all know that Jews regard the lost 10 tribes of Israel to be a people who had lost their identity since Assyria has invaded its land, a society which was polluted by pagan rituals. Jews regard them as dogs. They think that they are the only righteous people of God…
If someone will think along these lines…they will be able to connect it to the primary meaning of the parable of the Prodigal son.
…eventually, we will be able to connect this to the Acts of the Apostle, especially Stephen’s speech before his death.
The message will become clearer.
