'Flesh' in the Bible

yet you hate what is good, and love what is evil. You flay my people's skin and rip the flesh from their bones.

You devour my people's flesh, strip off their skin, and crush their bones. You chop them up like flesh in a pot -- like meat in a kettle.

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?
