In this passage as we might expect, the Israelites have returned not to God but to their rebellion. Their sin is ubiquitous in these 2 chapters. And, as is always the case, sin has consequences. This portion of Hosea shows what sin leads people away from.  It is wonderfully glorious and gracious that after all the Israelites have done to turn away from God, He still longs to shower them with righteousness.
(Hosea 9-10/Luke 23:27-43)
