Description is not the same as prescription. Or, to put it less technically, Old Testament historical passages are a questionable source of moral guidance for Christians.
We have noted previously that the book of Hosea goes back and forth between the historical account of Hosea’s marriage and the lessons God was drawing out of that relationship for Israel and, to a lesser extent, Judah. Hosea’s adulterous wife Gomer represented the idolatrous northern kingdom of Israel, while Hosea himself represented God.
Chapter 1 was more or less evenly split between history and prophecy. Chapter 2 was almost entirely prophetic. Chapter 3 takes us back to the historical narrative, and it is here that we have to be careful about the practical lessons we take out of the text for ourselves.
