Wherefore gloriest thou in the valleys, thy flowing valley, O backsliding daughter? that trusted in her treasures, saying, Who shall come unto me?
Thy flowing valley - rather, 'thy valley shall flow'-namely, with the blood of the slain; in sad contrast to their "valleys" in which they had heretofore "gloried," and which flowed with milk and honey (Grotius). Or else as margin, 'shall flow away.'
O backsliding daughter - apostate from Yahweh, the God of their father Lot, to Moloch.
That trusted in her treasures - her resources for resisting the foe (Jeremiah 48:7).
Who shall come unto thee? Who can come unto thee (Jeremiah 21:13, "Who shall come down against us? or who shall enter into our habitations?")
