When Yahweh spoke at the first by Hosea, Yahweh said to Hosea, "Go, take for yourself a wife of prostitution and children of unfaithfulness; for the land commits great adultery against from Yahweh."
Now that's a sad and a tragic day when God says, "Hey, I'm not going to have any more mercy upon them." They had existed solely because God's mercy. God had been so merciful to them. When God's mercy is taken away, there's nothing left. And so it was really a very severe judgment.
