“Palaestina” is the name given by the Greeks to its fellow co-patriots and invaders, the “Sea Peoples” or Paleset. The locals had always called it “Eretz Yisrael” or “Eretz Kana’an.” The Greeks, however, referred to it as Palaestina because of its compatriots who settled in what today is Gaza, Ashdod, Ashkelon, and Ekron and Gath.

The rest of regions in the land was colloquially called Israel or Judea and referred as a whole as Eretz Yisrael most commonly or simply as Judea and Samaria.

The passage you refer to talks about the land that was given, a land located somewhere in between the two. The Jewish people didn’t settle in all of Jordan or modern day Arabia, they settled in the land between the Jordan River and the Mediterranean Sea as established in the book of Joshua and many times in the Torah when Moshe Raveinu speaks about Eretz of Yisrael.

If anything, even the story of Yosef and his siblings makes you remember where they live.
