Context

“Huge bodies will be seen, devoid of life, carrying, in fierce haste, a multitude of men to the destruction of their lives. * ( Of Oxen, which are eaten. ) * The masters of estates will eat their own labourers. * ( Of beating Beds to renew them. ) * Men will be seen so deeply ungrateful that they will turn upon that which has harboured them, for nothing at all; they will so load it with blows that a great part of its inside will come out of its place, and will be turned over and over in its body. * ( Of Things which are eaten and which first are killed. )” source
