In this verse, Ezekiel delivers a message from the Lord to Pharaoh, the king of Egypt, declaring that he is like a great monster lying in the midst of his streams, claiming, 'My Nile is my own; I made it for myself.' This imagery symbolizes Pharaoh's pride and arrogance in thinking that his power and prosperity are self-made, rather than acknowledging God as the ultimate source of all blessings. The verse serves as a warning against human pride and self-sufficiency, reminding us of the importance of humility and recognizing God's sovereignty in our lives.
