Ephraim is a trained heifer that loves to thresh; So I will put a yoke on her beautiful neck. I will set a rider on Ephraim. Judah will plow. Jacob will break his clods.
"Judah shall plow, Judah shall break his clods ..." The southern kingdom will not be exempt.  Their gross sins, exactly like those of Ephraim will bring upon them exactly the same punitive judgment.  Judah was never for a moment left very far out of sight in the stern denunciations of this prophet.  Abused privilege results always in the loss of the privileges.  The metaphor of Hosea's marriage with Gomer also lies very close to the surface here.  She would not be a faithful wife; very well, her husband would employ her as a slave!  That is exactly what happened to the ancient Israel.
