What does Deuteronomy 2:12 mean?

The Horites used to live in Seir, but the descendants of Esau took over, drove them out, and settled there. Israel did the same thing in the land the Lord gave them to possess. Deuteronomy 2:12 - Modern Text Bible

(This verse draws a parallel: just as Esau’s descendants took over Seir from the Horites, Israel would take over their promised land.)
