"and My sword shall eat flesh": How is it possible for a sword to eat flesh? (The meaning is) rather: I shall make others eat from what My sword does. As it is written (Ezekiel 39:17-20) "Son of man, thus says the L-rd G-d: Say to every winged bird and to every beast of the field: Assemble and come, gather together from all around for the feast that I slaughter for you... And you will eat flesh and you will drink blood.
You will eat the flesh of warriors, and you will drink the blood of the princes of the land … And you will eat fats to satiety and you will drink blood to drunkenness … and you will be sated at My table," and (Isaiah 34:6) "The sword of the L-rd is full of blood, greased with fats." Why? (Ibid.) "For there is a sacrifice for the L-rd in Batzrah, a great slaughter in the land of Edom."
