Therefore thou shalt say unto them, Thus saith the LORD of hosts, the God of Israel; Drink ye, and be drunken, and spue, and fall, and rise no more, because of the sword which I will send among you.
Thus saith the Lord God of ... Israel ... fall, and rise no more - the pagan nations in question should fall to rise no more. The Jews should fall but for a time, and then rise again. Therefore the epithet is given, "the God of Israel."
