This represents Egypt no longer being proud of their strength. The reason that they will not be proud is that they will no longer be strong. Alternate translation: "Egypt will no longer be proud about being strong" or "Egypt will no longer have the strength that they were so proud of" (See:[[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-explicit]])
Ezekiel names towns on the borders of Egypt in order to refer to all of Egypt. Alternate translation: "In all of Egypt" or "From the northern border of Egypt to the southern border of Egypt" (See: [[rc://en/ta/man/jit/figs-merism]])
Yahweh speaks of himself by name to express the certainty of what he is declaring. See how you translated this in [Ezekiel 5:11](../05/11.md). Alternate translation: "this is what the Lord Yahweh has declared" or "this is what I, the Lord Yahweh, have declared" (See: [[rc://en/ta/man/jit/figs-123person]])
