You didn't read verse 31 very well: "the chief priests mocking said"
They MOCKED Jesus as a false King of Israel not the real King. He was Kind of a far away kingdom (heaven) NOT King of Israel during his first coming.
Yes, they were mocking Jesus. But it reveals that the Jews believe that the messiah will be the King of Israel.
If you go to any Jewish website, like Judaism 101, you will find that's what the Jews believe.
Traditional Jewish concept of the messiah (mashiach): what he will be like, what he will do, what the messianic age will be like, and why Jews do not believe Jesus was the messiah.

From that site....
"The term "mashiach" literally means "the anointed one," and refers to the ancient practice of anointing kings with oil when they took the throne. The mashiach is the one who will be anointed
as king in the End of Days."
Go to that site and educate yourself as to what the Jews believe. (I am not being condescending, just suggesting to help your understanding of what is going to happen.)
For example....
"Before the time of the mashiach, there shall be war and suffering (
Ezekiel 38:16)"
So, they are thinking that right after Gog/Magog event, their messiah will arrive. Isn't that what I have been telling you, that the Antichrist begins his 7 years time, during the 7 years that follow Gog/Magog in Ezekiel 39:9 ?
"The mashiach will be a great political leader descended from King David (
Jeremiah 23:5)."
The messiah will be a Jew. A great political leader. Who is like that on the world scene, today ? I am keeping an eye on Zelensky. The little horn person will wax strong from north and west of Israel, Daniel 8:9. i.e he comes into the middle east with a strong army.
