"Come, and let us return to Yahweh; For he has torn us to pieces, And he will heal us; He has injured us, And he will bind up our wounds.
We are in perfect agreement, that, if these three verses are a summary of what the people in Hosea's time were saying, or even thinking, they are woefully lacking as any true manifestation of genuine repentance; but this would not apply in the event of the passage being a prolepsis having reference to the "new life" that would arise from the stock of old Israel (in the person of Christ) at a much later time historically.  Our only real objection to the view of this place as the people's expression of a superficial and inadequate repentance is that it clouds what we believe to be the true view of verse 2 as a reference to the resurrection of Christ. And yet, even, such an ascription of the passage to the people of Hosea's day is not at all incompatible with what would be, in that case, an unconscious reference to the Lord's resurrection (as in the case of Caiaphas mentioned above).  Either interpretation is tenable.
