They build up Zion with blood, and Jerusalem with iniquity. Or, "O thou that buildest up" , &c. or "everyone of them that buildeth up" , &c. for the word is in the singular number; but, be fire words rendered either of these ways, they respect the heads and princes of the people; who either repaired the temple on Zion, or ornamented the king's palace, or built themselves fine stately houses in Jerusalem, or large streets there, by money they took of murderers to save them, as Kimchi; or by money got by rapine and oppression, by spoiling the poor of their goods and their livelihood, for them and their families, which was all one as shedding innocent blood; and by money obtained by bribes, for the perversion of justice, and such like illegal proceedings, truly called iniquity.
The Targum is,"who build their houses in Zion with bloodshed, and Jerusalem with deceits.'' hnwb "aedificans", Montanus, Munster, Burkius.
