'Territory' in the Bible

Thus says Yahweh: "For three transgressions of Ammon and for four I will not revoke [the punishment], because they ripped open the pregnant women of Gilead in order to enlarge their territory!

Cross over [to] Calneh and see, and go from there [to] Hamath Rabbah and go down [to] Gath of the Philistines. [Are] you better than these kingdoms, or is their territory greater than your territory?
