Introduction to Hosea

Hosea is supposed to have been of the kingdom of Israel. He lived and prophesied during a long period. The scope of his predictions appears to be, to detect, reprove, and convince the Jewish nation in general, and the Israelites in particular, of their many sins, particularly their idolatry: the corrupt state of the kingdom is also noticed. But he invites them to repentance, with promises of mercy, and gospel predictions of the future restoration of the Israelites and of the Jews, and their final conversion to Christianity.
