'Flesh' in the Bible

So I said, "I will not shepherd you! The [one] dying will die, and the [one] to be destroyed will be destroyed. And the [ones] remaining, let them devour {the flesh of each other}."

For look, I [am] raising up a shepherd in the land who will not attend to the [ones that are] perishing; he will not seek the young man, he will not heal the [ones that are] crushed and he will not sustain the healthy [ones]; he will devour the flesh of the {fattened ones} and tear apart [even] their hoofs.

And this will be the plague [with] which Yahweh will strike all the peoples that fight against Jerusalem: their flesh will rot while they [are] standing on their feet; their eyes will rot in their sockets, and their tongues will rot in their mouths.
