The prophet Hosea reports a decision of the people. They want to return to God. They are mathematically sure about his positive answer.
Then, the prophet answers, in the name of God. He reproaches their wishful thinking: their decisions are unstable like the morning dew that in no time disappears. Besides, they think that God likes material offerings and is satisfied by them.
Instead, God likes a steadfast effort, renewed every day, to be faithful to him. He likes the inner commitment to continually learn His ways.
