“he again came to the Sea of Galilee by way of Sidon.” This is not what we would normally expect. Sidon is about 25 miles north of Tyre, so instead of heading southeast to the Sea of Galilee, Jesus headed deeper into Gentile territory and went through Sidon, then did a sort of loop and turned southeast and went through the region of the Decapolis, which was also Gentile.

“Decapolis.” See commentary on Matthew 4:25.
