Charles Ellicott Commentary Ezekiel 30:12

"And I will make the rivers dry, and will sell the land into the hand of evil men; and I will make the land desolate, and all that is therein, by the hand of strangers: I, Jehovah, have spoken it." — Ezekiel 30:12 (ASV)

Make the rivers dry—that is, the canals of Egypt, by which the land was irrigated, and on which its fertility depended. It may also include the comparative drying, the lessening of the inundation of the Nile, which occurred from time to time, and was the cause of the various famines in Egypt mentioned in Scripture.
