Yahweh continues telling a parable to Ezekiel about a cooking pot that represents Jerusalem. This parable continues through the end of this verse. (See: [[rc://en/ta/man/jit/figs-parables]])
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]])
