had to go
Ἔδει δὲ αὐτὸν διέρχεσθαι διὰ τῆς Σαμαρίας.
John uniquely indicated that Jesus had to pass (Ἔδει δὲ αὐτὸν διέρχεσθαι) through Samaria (διὰ τῆς Σαμαρίας) because it was between the two areas of Judea in the south and Galilee in the north. Most Jewish people went around Samaria by going closer to the Jordan River. The Samaritans were not pure Hebrews, ever since the fall of Samaria and northern Israel in the 8th century BCE. They were a mixture of the left over 10 tribes during the Assyria captivity and those who came to Samaria as its foreign leaders. They had always opposed the Temple in Jerusalem even in the Israelite kingdom before the Exile, since they preferred to worship locally. Luke, chapter 9:51-56, had Jesus pass through Samaria on his way to Jerusalem from Galilee, not to Galilee, as here. Is there some Christian group that you do not believe that they are true Christians?
