What does Hosea 9:10 mean?

When I first found Israel, it was like finding grapes in the desert. When I saw your ancestors, it was like seeing the first figs of the season. But they went to Baal Peor and devoted themselves to shameful things, becoming as disgusting as what they loved. Hosea 9:10 - Modern Text Bible

(God once delighted in Israel, but their idolatry and immorality ruined that relationship.)
