We inform the king that, if this city is rebuilt and the walls finished, because of that you will then have no possession beyond the River.” Bible other translations

“beyond the River.” That is, on the other side of the Euphrates River. This is an exaggeration to incite the king of Persia, but one the king might have considered an actual possibility. There is very little chance that little Judah would be able to conquer the Middle East north to the Euphrates. They did not even control that territory under Solomon.
