'Flesh' in the Bible

I then said, "I will not shepherd you. What is to die, let it die, and what is to be eradicated, let it be eradicated. As for those who survive, let them eat each other's flesh!"

But this will be the nature of the plague with which the Lord will strike all the nations that have fought against Jerusalem: Their flesh will decay while they stand on their feet, their eyes will rot away in their sockets, and their tongues will dissolve in their mouths.
