Charles Ellicott Commentary Hosea 1:7

"But I will have mercy upon the house of Judah, and will save them by Jehovah their God, and will not save them by bow, nor by sword, nor by battle, by horses, nor by horsemen." — Hosea 1:7 (ASV)

Will save them ...—We may consider this verse to have been literally fulfilled in the destruction of Sennacherib’s army. The prophetic outlook anticipates the fact that when Judah is captive and exiled, her restoration by the divine hand would take the form of mercy and forgiveness. (Compare to Psalms 76:0, Isaiah 40:1–2).
