These are God's words to Pharaoh about Assyria. God gives his message in the form of a parable about a great cedar tree. (See: [[rc://en/ta/man/translate/figs-parables]])
In this parable, God speaks about Assyria as if it were a great tree to emphasize how great and powerful the Assyrians were. This parable continues until 31:9. AT: "Assyria was like a cedar" (See: [[rc://en/ta/man/translate/figs-parables]])
