The silver and gold are mine

The words "silver and gold" are a metonym for the treasures that the nations would bring into the temple (Haggai 2:7). (See: rc://en/ta/man/translate/figs-metonymy)

this is the declaration of Yahweh of hosts

Yahweh speaks of himself by name to express the certainty of what he is declaring. See how you translated this in Haggai 1:9. AT: "this is what Yahweh has declared" or "this is what I, Yahweh, have declared" (See: rc://en/ta/man/translate/figs-123person)
