It means God eating the devil. Remember the pharaoh and the snakes when the evil magicians of pharaoh threw down their stick and it turned into a snake but Moses threw down his stick and it turned into a snake and ate the other snake.

The Father is in control of all things and is the creator of all things so whatever He wants and does shall manifest you can fight Him, beat Him, throw stones at Him, but you can't defeat the Creator whom is perfect love and light, it's impossible for the creation cannot overcome the Creator! Yahshua I love you!
