We certify the king, that if this city be builded again, and the walls thereof set up,.... As it formerly was, and now attempted, as they suggest:
by this means thou shalt have no portion on this side the river; the river Euphrates; intimating that the Jews would not only shake off his yoke, and refuse to pay tribute themselves, but would seize on all his dominions on that side the river, and annex them to their own.

After thus casting suspicion upon the Jews as a seditious people, their adversaries bring the accusation, already raised at the beginning of the letter, to a climax, by saying that if Jerusalem is rebuilt and fortified, the king will lose his supremacy over the lands on this side the river. דּנה לקבל, on this account, for this reason, that the present inhabitants of the fortified city Jerusalem are like its former inhabitants, thou wilt have no portion west of Euphrates, i.e., thou wilt have nothing more to do with the countries on this side the river-wilt forfeit thy sway over these districts.
