What does Ezekiel 31:18 mean?

So, Pharaoh, who do you think you are compared to these trees of Eden? You’ll be brought down with the trees of Eden to the underworld. You’ll lie among the uncircumcised, with those killed by the sword. That’s what will happen to Pharaoh and all his people, says the Lord God. Ezekiel 31:18 - Modern Text Bible
