Psalms 63:10 - Matthew Poole's English Annotations on the Holy Bible

They shall fall by the sword, i.e. die in battle, as David foretold, 1 Samuel 26:10, and as was accomplished in Saul and his followers, who were David's greatest enemies, 1Sa 31. They shall be a portion for foxes; their carcasses shall be unburied upon the earth, and thereby become a prey to wild and ravenous creatures, and especially to foxes, which were in those parts in great abundance and which did and do feed not only upon fruits, Song of Solomon 2:15, but also upon flesh, as experience showeth. Besides, some very learned men think that the word rendered foxes is more general, and comprehends, besides foxes, another sort of creatures, like unto them called thoes, which were very numerous in this country; of which See Poole on "Judges 15:4".
