It is not known from other sources, so it is impossible to pin down. In Job, "The Land of Uz" is used as a sort of "far, far, away", where the story of Job, which is a parable, is set, not as a real country. Pretty much the same is true of "Qedem": it means "east", hence your translation of "orientals". For someone living and writing in Israel, "sons of the East" could mean nomads of the transjordanian desert, or inhabitants of the cities of Mesopotamia, or peoples of the Persian steppe.
BTW, the modern Hebrew translation of "The Wizard of Oz" is "Haqqosem Me'eretz Uz", which I think is pretty clever (I have no idea who came up with the idea).
