Isaiah 47:7 - Matthew Poole's English Annotations on the Holy Bible

These things; thy cruel usages of my people, and the heavy judgments which thou hadst reason to expect for them. The latter end of it; of that lady or of Babylon, and her glory and empire, or of thyself; here being a sudden change of the person, of which I have noted many examples in this prophet. The sense is, Thou wast besotted with the sense of thy present felicity, and didst not consider, as thy duty and common discretion obliged thee, what might and was likely to befall thee afterward; thou didst neither expect a change nor prepare for it.
