this is the declaration of the Lord Yahweh

Yahweh speaks of himself by name to express the certainty of what he is declaring. See how you translated a similar phrase in Jeremiah 1:8. AT: "this is what the Lord Yahweh has declared" or "this is what I, the Lord Yahweh, have declared" (See: rc://en/ta/man/translate/figs-123person)
