Turn to me ... and I will return to you

Yahweh speaks of having a change of attitude toward another person as if it were turning or returning. The people turning to Yahweh means that they will again be devoted to him and worship him, while Yahweh returning to the people means that he will again bless them and help them. (See: rc://en/ta/man/jit/figs-metaphor)

this is the declaration of Yahweh of hosts

Yahweh speaks of himself by name to express the certainty of what he is declaring. Alternate translation: "this is what Yahweh of hosts has declared" or "this is what I, Yahweh of hosts, have declared" (See: rc://en/ta/man/jit/figs-123person)
