Hos 3:1

1 Yihvah said to me, “Go again, love a woman loved by another, and an adulteress, even as Yihvah loves the children of Israel, though they turn to other gods, and love cakes of raisins.” 

Go again…just like the love of the LORD for children of Israel – here God prophecies the Revelation harlot, of the Gentiles, saying “Go again.” He has sent Hosea to a harlot once in recognition of the harlotry of the house of Israel, in Hos 1:2, and now after explaining the New Covenant with the Gentiles, God tells Hosea that he must “go again.” This is the end days purification of the kingdom of heaven that will pave the way for the salvation of Israel, which we read about in Rev 14, Luke 21:24 etc.

love the raisin cakes of the pagans – this will be the trouble of the Gentiles, who will mix pagan religious practices with the true faith.
