Charles Ellicott Commentary Ezekiel 29:5

"And I will cast thee forth into the wilderness, thee and all the fish of thy rivers: thou shalt fall upon the open field; thou shalt not be brought together, nor gathered; I have given thee for food to the beasts of the earth and to the birds of the heavens." — Ezekiel 29:5 (ASV)

Open fields is synonymous with “wilderness” in the previous clause. The crocodile and the fish together, drawn from the river, are to be thrown upon the sands of the neighboring desert, to be devoured by the birds and beasts of prey: thus representing that Pharaoh and his people, uprooted from their power, are to be given over as spoil to various nations.
