The Lord tells Ezekiel to prophesy against Pharaoh, and in the second half of verse 9 and into verse 10, He says, "Because you [Pharaoh] said, 'The Nile is mine, and I made it,' 10 therefore, behold, I am against you and against your streams, and I will make the land of Egypt an utter waste and desolation, from Migdol to Syene, as far as the border of Cush."
Pharaoh's claim that "The Nile is mine, and I made it" is very similar to what the Psalmist says of God in Psalm 95:5: "The sea is his, for he made it, and his hands formed the dry land." (I lookt up the Hebrew, and while most of it is beyond me, I did notice that both verses use the same verb for "made.") Pharaoh's claim is prideful and arrogant, but the Psalmist properly credits and (elsewhere in this Psalm) praises God for His creation.
As brief side notes:
"From Migdol to Syene" and "the sea/the dry land" are both merisms. The first seems simply to indicate a specific geographic area, but the second illustrates the variety and expanse of God's creation and - in turn - His powerful dominion over it.
Psalm 95:5 has a chiastic structure whose elements are features of God's creation ("the sea" and "the dry land") and the act of creation ("he made it" and "his hands formed"):
The sea is his
for he made it
and his hands formedthe dry land.
