'Flesh' in the Bible

Who hate the good, and love the evil; who pluck off their skin from off them, and their flesh from off their bones;

Who also eat the flesh of my people, and flay their skin from off them; and they break their bones, and chop them in pieces, as for the pot, and as flesh within the caldron.

Will the Lord accept a thousand rams, or ten thousand streams of olive oil? Should I give him my firstborn child as payment for my rebellion, my offspring -- my own flesh and blood -- for my sin?
