After Jesus talked to the Pharisees about washing
pots and pans and all their traditions, He rebuked
them for making the word nothing by doing them.

"Then Jesus went thence, and departed into the
coasts of Tyre and Sidon." Matthew 15:21

Jesus made a journey into a land beyond Israel.
Maybe it was to be alone with His disciples. Before
He had crossed over into the Gadarenes, and even
Galilee; but wasn't able to find seclusion. Now he
decided to go into Phoenicia where the people
were idolatrous and sinful and had been run off by
the Israelites. The Jews wouldn't ordinarily go near
this area so it may have been a good place to get
some rest. He wouldn't be recognized there.
