Jamieson, Fausset and Brown on Hosea 13:14

14. Applying primarily to God's restoration of Israel from Assyria partially, and, in times yet future, fully from all the lands of their present long-continued dispersion, and political death (compare Ho 6:2; Is 25:8; 26:19; Eze 37:12). God's power and grace are magnified in quickening what to the eye of flesh seems dead and hopeless (Ro 4:17, 19). As Israel's history, past and future, has a representative character in relation to the Church, this verse is expressed in language alluding to Messiah's (who is the ideal Israel) grand victory over the grave and death, the first-fruits of His own resurrection, the full harvest to come at the general resurrection; hence the similarity between this verse and Paul's language as to the latter (1Co 15:55). That similarity becomes more obvious by translating as the Septuagint, from which Paul plainly quotes; and as the same Hebrew word is translated in Ho 13:10, "O death, where are thy plagues (paraphrased by the Septuagint, 'thy victory')? O grave, where is thy destruction (rendered by the Septuagint, 'thy sting')?" The question is that of one triumphing over a foe, once a cruel tyrant, but now robbed of all power to hurt.

repentance shall be hid from mine eyes--that is, I will not change My purpose of fulfilling My promise by delivering Israel, on the condition of their return to Me (compare Ho 14:2-8; Nu 23:19; Ro 11:29).
