Adam Clarke on Hosea 6:1

Come, and let us return unto the Lord - When God had purposed to abandon them, and they found that he had returned to his place - to his temple, where alone he could be successfully sought; they, feeling their weakness, and the fickleness, weariness, and unfaithfulness of their idols and allies, now resolve to "return to the Lord;" and, referring to what he said, Hos 5:14 : "I will tear and go away;" they say, he "hath torn, but he will heal us;" their allies had torn, but they gave them no healing. While, therefore, they acknowledge the justice of God in their punishment, they depend on his well-known mercy and compassion for restoration to life and health.
