The concluding verse is at once a conclusion and commencement—an inference from what preceded, and the beginning of a second line of proof showing that, while their ruin was by themselves, their restoration would be by God. When the kings and princes whom they had sinfully sought, and who had been given to them in anger would fail, God himself would be their King, as is stated in Hosea 13:10 and Hosea 13:11. Further, when in consequence of their iniquities treasured up, their sorrows and sufferings would be extreme, as stated in Hosea 13:12 and Hosea 13:13, yet they would be raised up as out of their graves, as promised in Hosea 13:14.
Israel had shown contempt for Jehovah by putting confidence in kings of their own choice, yet these kings could not afford them help, whence the questions of Hosea 13:10. The usual rendering is at fault. I will be thy King. This should rather be, Where now is thy king? though ehi may be either verb or adverb. Where is any other that may says thee in all thy cities? Better take both clauses together and in connection, thus: Where, now, is thy king, that he may save thee in all thy cities?
