It's a reference to the Exodus. The man that comes back with Joshua saying the land can be captured is not a Jew and so he is given the outskirts of the promised land. Jesus makes a play on words. He is the new Joshua and the non-Jews are welcomed to the table, as was the plan before the Fall.
But yeah, keep reading bits of ancient texts of different genres apart from the whole. LOL
